We discuss and compare the charge-parity (CP) asymmetry in the charged Higgs boson decays H-->(u) over bar (i)d(j) for the second and third generation quarks in the minimal supersymmetric standard model. As part of the analysis, we derive some general analytical formulas for the imaginary parts of two-point and three-point scalar one-loop integrals and use them for calculating vectorial- and tensorial-type integrals needed for the problem under consideration. We find that, even though each decay mode has a potential to yield a CP asymmetry larger than 10%, further analysis based on the number of required charged Higgs events at colliders favors the (t) over barb, (c) over barb, and (c) over bars channels, whose asymmetry could reach 10%-15% in certain parts of the parameter space.

CP asymmetry in charged Higgs decays to chargino-neutralino pairs Frank, Mariana; Turan, İsmail (American Physical Society (APS), 2007-10-01) We analyze the charge-parity (CP) asymmetry in the charged Higgs boson decays to chargino-neutralino pairs, H-+/- -> chi(+/-)(i)chi(0)(j), i = 1, 2, j = 1,...,4. We show first that these modes have a large branching ratio for m(H)(+/-) greater than or similar to 600 GeV. We use Cutkosky rules to obtain the analytical formulas needed for the evaluation of the asymmetry under consideration. We then calculate the CP asymmetry in chargino-neutralino decays by including supersymmetric mass bounds, as well as con...
CP violation in the radiative dileptonic B-meson decays Erkol, G; Turan, Gürsevil (IOP Publishing, 2002-12-01) We investigate the CP violating asymmetry, the forward-backward asymmetry and the CP violating asymmetry in the forward-backward asymmetry for the radiative dileptonic B-meson decays B-d --> gammal(+)l(-) for the f = e, mu, tau channels. It is observed that these asymmetries are quite sizable and B-d --> gamma l(+)l(-) decays seem promising for investigating CP violation.
Measurement of the charge asymmetry in top-quark pair production in proton-proton collisions at root s=7 TeV Chatrchyan, S.; et. al. (Elsevier BV, 2012-03-01) The difference in angular distributions between top quarks and antiquarks, commonly referred to as the charge asymmetry, is measured in pp collisions at the LHC with the CMS experiment. The. data sample corresponds to an integrated luminosity of 1.09 fb(-1) at a centre-of-mass energy of 7 TeV. Top-quark pairs are selected in the final state with an electron or muon and four or more jets. At least one jet is identified as originating from b-quark hadronization. The charge asymmetry is measured in two variabl...
Strange particle production in pp collisions at root s=0.9 and 7 TeV Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2011-05-01) The spectra of strange hadrons are measured in proton-proton collisions, recorded by the CMS experiment at the CERN LHC, at centre-of-mass energies of 0.9 and 7TeV. The K-S(0), A, and Xi(-) particles and their antiparticles are reconstructed from their decay topologies and the production rates are measured as functions of rapidity and transverse momentum, p(T). The results are compared to other experiments and to predictions of the PYTHIA Monte Carlo program. The p(T) distributions are found to differ subst...
Observation of a new boson with mass near 125 GeV in pp collisions at root s=7 and 8 TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2013-06-01) A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample corresponds to integrated luminosities up to 5.1 fb(-1) at root s = 7 TeV, and up to 5.3 fb(-1) at root s = 8 TeV. The results for five Higgs boson decay modes gamma gamma, ZZ, WW, tau tau, and bb, which show a combined local significance of 5 standard deviations near 125 GeV, are reviewed. ...
