The sensitivities of the one-spin and two-spin polarization observables for p+(p) over bar --> P-0+V-0. with P-0 = pi(0).eta.eta' and V-0 = p.omega.phi. based on the triplet enhancement hypothesis for strangeness production in p (p) over bar collisions are analyzed. The analysis is carried out under special kinematical conditions where the P-0 meson production angle in the CMS is equal to pi/2, for which C-invariance of strong interactions reduces the number of independent amplitudes to three.

Flavor-changing neutral currents transition of the Sigma(Q) to nucleon in full QCD and heavy quark effective theory AZİZİ, KAZEM; BAYAR, MELAHAT; Zeyrek, Mehmet Tevfik (IOP Publishing, 2010-08-01) The loop-level flavor-changing neutral currents transitions of the Sigma(b) -> nl(+)l(-) and Sigma(c) -> pl(+)l(-) are investigated in full QCD and heavy quark effective theory in the light cone QCD sum rules approach. Using the most general form of the interpolating current for Sigma(Q), Q = b or c, as members of the recently discovered sextet heavy baryons with spin 1/2 and containing one heavy quark, the transition form factors are calculated using two sets of input parameters entering the nucleon distri...
Exclusive B ->rho l(+)l(-) decay and polarized lepton pair forward-backward asymmetries Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2006-02-01) The polarized lepton pair forward-backward asymmetries in B ->rho l(+)l(-) decay using a general, model independent form of the four-Fermi interaction is studied. The general expressions for nine double-lepton polarization forward-backward asymmetries are calculated. The study of the forward-backward asymmetries of the doubly polarized lepton pair proves to be a very useful tool in looking for new physics beyond the standard model.
Measurement of normalized differential t(t)over-bar cross sections in the dilepton channel from pp collisions at root s=13 TeV Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2018-04-01) Normalized differential cross sections for top quark pair production are measured in the dilepton (e(+)e(-), mu(+)mu(-), and mu(-/+),e(+/-)) decay channels in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements are performed with data corresponding to an integrated luminosity of 2.1 fb(-1) using the CMS detector at the LHC. The cross sections are measured differentially as a function of the kinematic properties of the leptons, jets from bottom quark hadronization, top quarks, and...
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...
Multiparticle correlations and higher order harmonics in pPb collisions at root s(NN)=8.16 TeV Wang, Quan; et. al. (Elsevier BV, 2019-02-01) The elliptic and higher-order azimuthal anisotropy Fourier harmonics (v(n)) are obtained for pPb collisions at root s(NN) = 8.16 TeV over a wide range of event multiplicities based on multiparticle correlations. The data were collected by the CMS experiment during the 2016 LHC run. A sample of peripheral PbPb collisions at root s(NN) = 5.02 TeV covering a similar range of event multiplicities to the pPb results is also analyzed for comparison. The ratios of different harmonic moments are obtained for both v...
