    Suppression of Excited States Relative To the Ground State in Pb-Pb Collisions at S Nn = 5.02 Tev
    (American Physical Society, 2018) CMS Collaboration; Karapınar, Güler
    The relative yields of mesons produced in pp and Pb-Pb collisions at sNN=5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are formed by comparing the yields of the excited states, (2S) and (3S), to the ground state, (1S), in both Pb-Pb and pp collisions at the same center-of-mass energy. The double ratios, [(nS)/(1S)]Pb-Pb/[(nS)/(1S)]pp, are measured to be 0.308±0.055(stat)±0.019(syst) for the (2S) and less than 0.26 at 95% confidence level for the (3S). No significant (3S) signal is found in the Pb-Pb data. The double ratios are studied as a function of collision centrality, as well as transverse momentum and rapidity. No significant dependencies are observed.

    Henry's Law Constant, Octanol-Air Partition Coefficient and Supercooled Liquid Vapor Pressure of Carbazole as a Function of Temperature: Application To Gas/Particle Partitioning in the Atmosphere
    (Elsevier Ltd., 2006) Odabaşı, Mustafa; Çetin, Banu; Sofuoğlu, Aysun
    The Henry's law constant for carbazole was experimentally determined between 5 and 35°C using a gas-stripping technique. The following equation was obtained for dimensionless Henry's law constant (H′) versus temperature (T, K):lnH′=-3982(T,K)-1+1.01 Temperature-dependent octanol-air partition coefficients (KOA) and supercooled liquid vapor pressures (PL, Pa) of carbazole were also determined using the GC retention time method. The temperature dependence of KOA and PL were explained by the following:logKOA=4076/(T,K)-5. 65logPL(Pa)=-3948(T,K)-1+11.84 The gas and particle-phase carbazole concentrations measured previously in Chicago, IL in 1995 was used for gas/particle partitioning modeling. Octanol based absorptive partitioning model consistently underpredicted the gas/particle partition coefficients (K p) for all sampling periods. However, overall there was a good agreement between the measured Kp and soot-based model predictions.
