We suggest to measure the triple polarization correlations in the exclusive associative charm particle photoproduction, (gamma) over right arrow+(p) over right arrow-->Lambda(c)(+)+ (D-0) over bar with linearly polarized photons, as a method to determine the P parity of the charmed D meson. The dependence of these correlations on the parity P(NLambda(c)D) can be predicted in a model independent way. The t dependence of the differential cross section for vector meson photoproduction, gamma + p --> Lambda(c)(+)+ (D*(0)) over bar, in a model based on D exchange, is also sensitive to P(NLambda(c)D).

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...
Search for the production of dark matter in association with top-quark pairs in the single-lepton final state in proton-proton collisions at root s=8 TeV Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2015-06-01) A search is presented for particle dark matter produced in association with a pair of top quarks in pp collisions at a centre-of-mass energy of root s = 8TeV. The data were collected with the CMS detector at the LHC and correspond to an integrated luminosity of 19.7 fb(-1). This search requires the presence of one lepton, multiple jets, and large missing transverse energy. No excess of events is found above the SM expectation, and upper limits are derived on the production cross section. Interpreting the fi...
a(0)K(+)K(-) vertex in light cone QCD sum rules Gokalp, A; Yılmaz, Osman (American Physical Society (APS), 2004-04-01) We investigate the a(0)K(+)K(-) vertex in the framework of light cone QCD sum rules. We estimate the coupling constant g(a0)K(+)K(-) which is an essential ingredient in the analysis of physical processes involving the a(0)(980) meson. Our result is somewhat larger than the previous determinations of this coupling constant.
t -> cg,c gamma,cZ in the left-right supersymmetric model Frank, M; Turan, İsmail (American Physical Society (APS), 2005-08-01) We analyze top-quark flavor violating decays into a charm quark and a gluon, photon, or Z boson in a supersymmetric model incorporating left-right symmetry. We include loop calculations involving contributions from scalar quarks, gluinos, charginos, and neutralinos. We perform the calculations first assuming the minimal (flavor-diagonal) scalar quark scenario and then allowing for arbitrary mixing between the second and the third generation of scalar quarks, in both the up and the down sectors. In each case...
B decays in an asymmetric left-right model Frank, Mariana; Hayreter, Alper; Turan, İsmail (American Physical Society (APS), 2010-08-25) Motivated by recently observed disagreements with the standard model predictions in B decays, we study b -> d, s transitions in an asymmetric class of SU(2)(L) x SU(2)(R) x U(1)(B-L) models, with a simple one-parameter structure of the right-handed mixing matrix for the quarks, which obeys the constraints from kaon physics. We use experimental constraints on the branching ratios of b -> s gamma, b -> ce (nu) over bar (e), and B-d,s(0) - (B) over barB(d,s)(0) mixing to restrict the parameters of the model: g...
