We give a review and present a comprehensive calculation for the leptonic constant fB(c) of the low-lying pseudoscalar and vector states of B-c-meson in the framework of static and QCD-motivated nonrelativistic potential models taking into account the one-loop and two-loop QCD corrections in the short distance coefficient that governs the leptonic constant of B-c quarkonium system. Further, we use the scaling relation to predict the leptonic constant of the nS-states of the bc system. Our results are compared with other models to gauge the reliability of the predictions and point out differences.

Short-range form of the charge distribution of4He and its charge form factor Lodhi, M. A. K.; Ray, A. K.; Yalçın, C (Springer Science and Business Media LLC, 1989-2) We discuss the influence of the short-range correlation on the charge distribution and elastic charge from factor of4He and present the numerical results. The charge density oscillates at the centre of the nucleus as higher-order terms from the cluster expansion are included. The second minimum and the third maximum are produced in the charge form factor with the fully correlated wave function or when sufficiently higher-order terms are included in the calculations.
Calculation of the phase diagram using the Landau-mean-field theory for K2S2O7-KHSO4 Sen, S.; Yurtseven, Hasan Hamit (Elsevier BV, 2009-03-15) In this study a T-X phase diagram of K2S2O7-KHSO4 is calculated using the Landau-mean-field theory. By expanding the free energies of the solid phases of I, II and III in terms of the order parameters, the phase line equations are obtained among the following transitions: liquid-solid I, liquid-solid II, solid I-solid II, solid II solid III and liquid-solid III in K2S2O7-KHSO4.
Measurement of the W(+/-)Z production cross section and limits on anomalous triple gauge couplings in proton-proton collisions at root s=7 TeV with the ATLAS detector Aad, G.; et. al. (Elsevier BV, 2012-03-23) This Letter presents a measurement of W(+/-)Z production in 1.02 fb(-1) of pp collision data at root s = 7 TeV collected by the ATLAS experiment in 2011. Doubly leptonic decay events are selected with electrons, muons and missing transverse momentum in the final state. In total 71 candidates are observed, with a background expectation of 12.1 +/- 1.4(stat.)(-2.0)(+4.1)(syst.) events. The total cross section for W(+/-)Z production for Z/gamma* masses within the range 66 GeV to 116 GeV is determined to be sig...
Determination of the strong coupling constant alpha(S)(m(Z)) from measurements of inclusive W-+/- and Z boson production cross sections in proton-proton collisions at root s=7 and 8 TeV Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2020-06-01) Twelve measurements of inclusive cross sections of W-+/- and Z boson production, performed in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, are compared with perturbative quantum chromodynamics calculations at next-to-next- to-leading order (NNLO) accuracy obtained with the CT14, HERAPDF2.0, MMHT14, and NNPDF3.0 parton distribution functions (PDFs). Data and theory agree well for all PDF sets, taking into account the experimental and theoretical uncertainties. A novel procedure is empl...
Measurement of the differential and double-differential Drell-Yan cross sections in proton-proton collisions at root s=7 TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2013-12-01) Measurements of the differential and double-differential Drell-Yan cross sections are presented using an integrated luminosity of 4.5 (4.8) fb(-1) in the dimuon (dielectron) channel of proton-proton collision data recorded with the CMS detector at the LHC at = 7 TeV. The measured inclusive cross section in the Z-peak region (60-120 GeV) is sigma(a""a"") = 986.4 +/- 0.6 (stat.) +/- 5.9 (exp. syst.) +/- 21.7 (th. syst.) +/- 21.7 (lum.) pb for the combination of the dimuon and dielectron channels. Differential...
