The contribution of the fourth generation quarks to the rare B-s --> l(+)l(-) and B-s --> l(+)l(-)gamma decays are studied. Constraints on the extended Cabibbo-Kobayashi-Maskawa matrix elements \VtbV*(ts)\ and \Vt'bV*(t's)\, are obtained from the existing experimental result for the branching ratio of the B --> X(s)gamma decay. The branching ratios of the above-mentioned decays, as well as the photon spectrum in the B-s --> l(+)l(-)gamma decay, are studied. It is found that the results are sensitive to the existence of the fourth generation.

Fourth generation effects in processes induced by the b -> s transition Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (Springer Science and Business Media LLC, 2003-07-01) We study the effects of sequential fourth quark generation in rare B --> K(K*)l(+)l(-) decays induced by the b --> s transition and in B-s(0)-(B) over bar (0)(s) mixing. Using the experimental values on the branching ratios of the B --> X(s)gamma and B --> K(K*)l(+)l(-) decays, the allowed regions for \VtbVts*\ and \Vt'bVt's*\ are determined as a function of the t' quark mass.
Analysis of various polarization asymmetries in the inclusive b -> s a"" (+) a"" (-) decay in the fourth-generation standard model BASHIRY, VALİ; Bayar, M. (Springer Science and Business Media LLC, 2009-06-01) In this study a systematical analysis of various polarization asymmetries in inclusive b -> s a"" (+) a"" (-) decay in the standard model (SM) with four generation of quarks is carried out. We found that the various asymmetries are sensitive to the new mixing and quark masses for both of the mu and tau channels. Sizable deviations from the SM values are obtained. Hence, b -> s a"" (+) a"" (-) decay is a valuable tool for searching physics beyond the SM, especially in the indirect searches for the fourth-gen...
Novel RDX-Based Cage and Cage-Like Nitramines Türker, Burhan Lemi; Bayar, Caglar Celik; Turhan, Hamza (Informa UK Limited, 2013-10-01) 1,3,5-Trinitroperhydro-1,3,5-triazine (RDX)-based cage and cage-like nitramines in which two RDX molecules are linked to each other via three and two carbon atoms, respectively, have been investigated computationally using density functional theory (DFT) at a B3LYP/6-31G(d,p) theoretical level. The study focused on finding out how the quantum chemical and detonation properties of RDX change if two RDX molecules come together and form these structures. Both considered nitramines exhibited higher heats of for...
Forward-backward asymmetry of Drell-Yan lepton pairs in pp collisions at root s=8 TeV Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2016-06-01) A measurement of the forward-backward asymmetry A(FB) of oppositely charged lepton pairs (mu mu and ee) produced via Z/gamma* boson exchange in pp collisions at root s = 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.7 fb(-1) collected with the CMS detector at the LHC. The measurement of AFB is performed for dilepton masses between 40 GeV and 2 TeV and for dilepton rapidity up to 5. The AFB measurements as a function of dilepton mass and rapidity are compared with the stan...
New physics effects in the rare B-s -> gamma l(+)l(-) decays with a polarized photon Yilmaz, UO; Sirvanli, BB; Turan, Gürsevil (Springer Science and Business Media LLC, 2003-09-01) Using the most general model independent form of the effective Hamiltonian, the rare B-s --> gammal(+)l(-) decays are studied by taking into account the polarization of the photon. The total and the differential branching ratios for these decays, when the photon is in the positive or the negative helicity state, are presented. The dependence of these observables on the new Wilson coefficients is studied. Also is investigated the sensitivity of the 'photon polarization asymmetry' in B-s-->gammal(+)l(-) decay...
