This study investigates the influence of fourth-generation quarks on double-lepton polarizations in the B -> Kl(+) l(-) decay. Taking vertical bar Vt'sVt'b vertical bar similar to {0.01 - 0.03} with a phase of about 100 degrees, which is consistent with the b -> sl(+) l(-) rate and the B-s mixing parameter Delta m B-s, we have found out that double-lepton (mu, tau) polarizations are quite sensitive to the existence of the fourth generation. It can serve as an efficient tool to search for new physics effects, precisely to an indirect search for the fourth-generation quarks (t', b').

The effects of non-universal extra dimensions on the fermion electric dipole moments in the two Higgs doublet model Iltan, EO (Springer Science and Business Media LLC, 2004-04-01) We study the the effects of non-universal extra dimensions on the electric dipole moments of fermions in the two Higgs doublet model. We observe that the t quark and b quark electric dipole moments are sensitive to the extra dimensions, however, in the case of charged lepton electric dipole moments, this sensitivity is relatively weak.
Measurement of the production cross section of prompt j/psi mesons in association with a W (+/-) boson in pp collisions root s=7 TeV with the ATLAS detector Aad, G.; et. al. (Springer Science and Business Media LLC, 2014-04-01) The process pp -> W (+/-) J/psi provides a powerful probe of the production mechanism of charmonium in hadronic collisions, and is also sensitive to multiple parton interactions in the colliding protons. Using the 2011 ATLAS dataset of 4.5 fb(-1) of root s= 7 TeV pp collisions at the LHC, the first observation is made of the production of W (+/-) + prompt J/psi events in hadronic collisions, using W (+/-) -> mu nu(mu) and J/psi -> mu(+)mu(-) center dot A yield of W (+/-) + prompt J/psi events is observed, w...
Study of W boson production in pPb collisions at root(NN)-N-S=5.02 TeV Adam, W.; et. al. (Elsevier BV, 2015-11-01) The first study of W boson production in pPb collisions is presented, for bosons decaying to a muon or electron, and a neutrino. The measurements are based on a data sample corresponding to an integrated luminosity of 34.6 nb(-1) at a nucleon-nucleon centre-of-mass energy of root(NN)-N-S = 5.02 TeV, collected by the CMS experiment. The W boson differential cross sections, lepton charge asymmetry, and forward-backward asymmetries are measured for leptons of transverse momentum exceeding 25 GeV/c, and as a fu...
Search for a light charged Higgs boson in top quark decays in pp collisions at root s=7 TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2012-07-01) Results are presented on a search for a light charged Higgs boson that can be produced in the decay of the top quark t -> H(+)b and which, in turn, decays into tau(+)nu(tau). The analysed data correspond to an integrated luminosity of about 2 fb(-1) recorded in proton-proton collisions at root s = 7 TeV by the CMS experiment at the LHC. The search is sensitive to the decays of the top quark pairs t (t) over bar -> H(+/-)W(-/+)b (b) over bar and t (t) over bar -> H +/- H -/+ b (b) over bar. Various final sta...
Search for narrow resonances using the dijet mass spectrum in pp collisions at root s=8 TeV Chatrchyan, S.; et. al. (American Physical Society (APS), 2013-06-01) Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at √s=8 TeV. The data sample corresponds to an integrated luminosity of 4.0 fb−1, collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying ...
