    Eu as a Good (enough) Governance Exporter in Kosovo? Local Views on the Aborted Kosovo E Re Power Plant Project
    (Springer, 2022) Buhari Gülmez, Didem; Aydın Dikmen, Bengü
    This study focuses on the EU's perceived role in Kosovo as a good governance exporter through political conditionality. Local debates on the EU's stance towards the recently aborted coal power plant project (Kosovo e Re) reflect a disappointment with the EU's failure to prioritise good governance reforms that have not been implemented sufficiently in Kosovo. The study mainly benefits from interviews conducted in Pristina in 2019 in order to explore various EU, domestic and international factors hindering the EU's capability as a good governance exporter. Following the EU's limited transformative agency in contested states, it concludes that the EU is perceived by local actors in Kosovo as a "good enough governance" exporter that favours stability in the region and transatlantic partnership at the expense of good governance reforms. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

    Field Experiments in Bargaining
    (Springer, 2022) Dindaroğlu, Burak; Ertaç, Seda
    Understanding price formation and surplus division in bargaining contexts has long been of interest to economists. Laboratory experiments contribute to our understanding of bargaining by inducing valuations and costs, which are usually unobserved in natural negotiation settings, and allow control over the negotiation process. Field experiments, on the other hand, allow economists to study bargaining in more natural contexts with higher external validity, and can be particularly useful when bargaining behavior draws on context-specific characteristics and experiences that may be stripped in lab settings or involves biases that would not surface under observability. In this chapter, we provide an overview of field experiments studying bargaining behavior and outcomes in a variety of settings, from bargaining for auto rickshaw to markets for livestock. We offer a methodological discussion, position field experiments in bargaining in the tradition of field experiments in economics at large, and highlight difficulties in the design and implementation of fieldwork for such environments. We also discuss potential areas and issues where future field experiments are of special importance for understanding price formation in bargaining. © The Editor(s) (if applicable) and The Author(s), under exclusive licence to Springer Nature Switzerland AG 2022.

    Destined for Coal?: a "hierarchy of Harms" and the Prospects of Renewable Energy in Kosovo
    (Springer, 2022) Aydın Dikmen, Bengü; Buhari Gülmez, Didem
    Relying on interviews conducted in the summer of 2019 with parliamentary advisors, civil society activists, public officials and the EU, OSCE, and UNDP missions in Kosovo, this study provides an overview of the debates about the building of the new coal power plant by a US-led (UK-based) Company ContourGlobal. It discusses how different actors in Kosovo state and society approach the renewable energy question. An important obstacle against Kosovo's transition to renewable energy derives from the absence of consensus about the main threats and goals facing Kosovo. In this context, rationalist and constructivist stances imply different "hierarchies of harms". © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022. All rights reserved.

    Search for Strongly Interacting Massive Particles Generating Trackless Jets in Proton-Proton Collisions at Root S=13 Tev
    (Springer, 2022) Karapınar, Güler; CMS Collaboration
    A search for dark matter in the form of strongly interacting massive particles (SIMPs) using the CMS detector at the LHC is presented. The SIMPs would be produced in pairs that manifest themselves as pairs of jets without tracks. The energy fraction of jets carried by charged particles is used as a key discriminator to suppress efficiently the large multijet background, and the remaining background is estimated directly from data. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 16.1 fb(-1), collected with the CMS detector in 2016. No significant excess of events is observed above the expected background. For the simplified dark matter model under consideration, SIMPs with masses up to 100 GeV are excluded and further sensitivity is explored towards higher masses.

    Search for New Physics in the Lepton Plus Missing Transverse Momentum Final State in Proton-Proton Collisions at Root S=13 Tev
    (Springer, 2022) Karapınar, Güler; CMS Collaboration
    A search for physics beyond the standard model (SM) in final states with an electron or muon and missing transverse momentum is presented. The analysis uses data from proton-proton collisions at a centre-of-mass energy of 13 TeV, collected with the CMS detector at the LHC in 2016-2018 and corresponding to an integrated luminosity of 138 fb(-1). No significant deviation from the SM prediction is observed. Model-independent limits are set on the production cross section of W' bosons decaying into lepton-plus-neutrino final states. Within the framework of the sequential standard model, with the combined results from the electron and muon decay channels a W' boson with mass less than 5.7 TeV is excluded at 95% confidence level. Results on a SM precision test, the determination of the oblique electroweak W parameter, are presented using LHC data for the first time. These results together with those from the direct W' resonance search are used to extend existing constraints on composite Higgs scenarios. This is the first experimental exclusion on compositeness parameters using results from LHC data other than Higgs boson measurements.

    Search for Single Production of a Vector-Like T Quark Decaying To a Top Quark and a Z Boson in the Final State With Jets and Missing Transverse Momentum at Root S=13 Tev
    (Springer, 2022) Karapınar, Güler; CMS Collaboration
    A search is presented for single production of a vector-like T quark with charge 2/3 e, in the decay channel featuring a top quark and a Z boson, with the top quark decaying hadronically and the Z boson decaying to neutrinos. The search uses data collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 137 fb(-1) recorded at the CERN LHC in 2016-2018. The search is sensitive to a T quark mass between 0.6 and 1.8 TeV with decay widths ranging from negligibly small up to 30% of the T quark mass. Reconstruction strategies for the top quark are based on the degree of Lorentz boosting of its final state. At 95% confidence level, the upper limit on the product of the cross section and branching fraction for a T quark of small decay width varies between 15 and 602 fb, depending on its mass. For a T quark with decay widths between 10 and 30% of its mass, this upper limit ranges between 16 and 836 fb. For most of the studied range, the results provide the best limits to date. This is the first search for single T quark production based on the full Run 2 data set of the LHC.

    Search for a Heavy Higgs Boson Decaying Into Two Lighter Higgs Bosons in the Tau Tau Bb Final State at 13tev
    (Springer, 2021) Karapınar, Güler; CMS Collaboration
    A search for a heavy Higgs boson H decaying into the observed Higgs boson h with a mass of 125 GeV and another Higgs boson h(S) is presented. The h and h(S) bosons are required to decay into a pair of tau leptons and a pair of b quarks, respectively. The search uses a sample of proton-proton collisions collected with the CMS detector at a center-of-mass energy of 13TeV, corresponding to an integrated luminosity of 137 fb(-1). Mass ranges of 240-3000 GeV for m(H) and 60-2800 GeV for m(hS) are explored in the search. No signal has been observed. Model independent 95% confidence level upper limits on the product of the production cross section and the branching fractions of the signal process are set with a sensitivity ranging from 125 fb (for m(H) = 240 GeV) to 2.7 fb (for m(H) = 1000 GeV). These limits are compared to maximally allowed products of the production cross section and the branching fractions of the signal process in the next-to-minimal supersymmetric extension of the standard model.

    Measurements of the Pp -> W-+/-gamma Gamma and Pp -> Z Gamma Gamma Cross Sections at Root S=13 Tev and Limits on Anomalous Quartic Gauge Couplings
    (Springer, 2021) Karapınar, Güler
    The cross section for W or Z boson production in association with two photons is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV. The data set corresponds to an integrated luminosity of 137 fb(-1) collected by the CMS experiment at the LHC. The W -> l nu and Z -> ll decay modes (where l = e, mu) are used to extract the W gamma gamma and Z gamma gamma cross sections in a phase space defined by electron (muon) with transverse momentum larger than 30 GeV and photon transverse momentum larger than 20 GeV. All leptons and photons are required to have absolute pseudorapidity smaller than 2.5. The measured cross sections in this phase space are sigma(W gamma gamma) = 13.6(-1.9)(+1.9) (stat)(-4.0)(+4.0) (syst) +/- 0.08 (PDF + scale) fb and sigma(Z gamma gamma) = 5.41(-0.55)(+0.58) (stat)(-0.70)(+0.64) (syst) +/- 0.06 (PDF + scale) fb. Limits on anomalous quartic gauge couplings are set in the framework of an effective field theory with dimension-8 operators.
