We examine the possibility for precise determination of /V-ts/ (and /V-td/V-ts/) from the exclusive decays, B --> Kl(+)l(-), B --> K*l(+)l(-) (and B --> pi l(+)l(-), B --> rho l(+)l(-)). We show that the ratio /V-ts/ can be extracted experimentally with a small theoretical uncertainty from hadronic form-factors, if we appropriately constrain kinematical regions of q(2). We also give detailed analytical and numerical results on the differential decay width d Gamma(B --> K*l(+)l(-))/dq(2), and the ratios of integrated branching fractions, B(B --> rho l(+)l(-))/B(B --> K*l(+)l(-)). We estimate that one can determine the ratio /V-ts/ from those decays within theoretical accuracy of similar to 10%.

Measurement of the mass of the top quark in decays with a J/psi meson in pp collisions 8 Tev Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2016-12-01) A first measurement of the top quark mass in the decay channel t -> (W -> l nu)(b -> J/psi + X -> mu(+) + mu(-) + X) is presented. The analysis uses events selected from the proton-proton collisions recorded by the CMS detector at the LHC at a center-of-mass energy of 8TeV. The data correspond to an integrated luminosity of 19.7 fb(-1), with 666 t (t) over bar and single top quark candidate events containing a reconstructed J/psi candidate decaying into an oppositely-charged muon pair. The mass of the (J/ps...
Exclusive gamma gamma -> mu(+)mu(-) production in proton-proton collisions at root s=7TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2012-01-01) A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at root s = 7 TeV, pp -> p mu(+)mu(-) p, is reported using data corresponding to an integrated luminosity of 40 pb-1. For muon pairs with invariant mass greater than 11.5 GeV, transverse momentum p(T)(mu) > 4 GeV and pseudorapidity 1770.1) p mu(+)mu(-) p) - 3.38(-0.55)(+0.58) (stat.)+/- 0.16 (syst.) +/- 0.14 (lumi.) pb, consistent with the theoretical prediction evaluated with the event generator LPAIR. The ratio...
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.
HIGHER-DERIVATIVE EFFECTIVE YANG-MILLS THEORY AND STATIC SPHERICALLY SYMMETRICAL FIELD CONFIGURATIONS BASKAL, S; DERELI, T (IOP Publishing, 1993-04-01) The variational field equations and the covariantly conserved energy-momentum tensor of a higher-derivative effective Yang-Mills theory are given. A class of static spherically symmetric gauge field configurations that follow from the Wu-Yang ansatz is considered.
Dualisation of the Salam-Sugin D-8 supergravity Dereli, T; Yilmaz, NT (Elsevier BV, 2004-07-19) The first-order formulation of the Salam-Sezgin D = 8 supergravity coupled to N vector multiplets is discussed. The non-linear realization of the bosonic sector of the D = 8 matter coupled Salam-Sezgin supergravity is introduced by the dualisation of the fields and by constructing the Lie superalgebra of the symmetry group of the doubled field strength.
