CP violation in the inclusive b -> sg decay in the framework of multi-Higgs-doublet models

Goksu, A
Iltan, EO
Solmaz, L
We study the decay width and CP asymmetry of the inclusive process b-->sg (g denotes gluon) in the multi-Higgs-doublet models with complex Yukawa couplings, including next to leading QCD corrections. We analyze the dependences of the decay width and CP asymmetry on the scale mu and CP-violating parameter theta. We observe that there exists an enhancement in the decay width and CP asymmetry is at the order of 10(-2).


Radiative decays of the heavy tensor mesons in light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2019-01-11)
The transition form factors of the radiative decays of the heavy tensor mesons to heavy pseudoscalar and heavy vector mesons are calculated in the framework of the light-cone QCD sum rules method at the point Q(2) = 0. Using the obtained values of the transition form factors at the point Q(2) = 0, the corresponding decay widths are estimated. The results show that the radiative decays of the heavy-light tensor mesons could potentially be measured in the future planned experiments at LHCb.
CP violation in polarized B -> pi l(+)l(-) and B -> pl(+)l(-) decays
Erkol, G; Wagenaar, JW; Turan, Gürsevil (Springer Science and Business Media LLC, 2005-05-01)
We study the decay rate and the CP violating asymmetry of the exclusive B -> pi l(+)l(-) and B -> rho l(+)l(-) decays in the case where one of the final leptons is polarized. We calculate the contributions coming from the individual polarization states in order to identify a so-called wrong sign decay, which is a decay with a given polarization, whose width and CP asymmetry are smaller as compared to the unpolarized one. The results are presented for electrons and tau leptons. We observe that in particular ...
Electroweak theory and non-commutative geometry
Catal-Ozer, A; Dereli, T (IOP Publishing, 2001-08-21)
The non-commutative generalization of the standard electroweak model due to Balakrishna, Gursey and Wali is formulated in terms of the derivations Der(2)(M-3) of a three-dimensional representation of the su(2) Lie algebra of weak isospin. A light Higgs boson of mass about 130 GeV, together with four very heavy scalar bosons are predicted.
Spherically symmetric solutions of Einstein plus non-polynomial gravities
Deser, S.; Sarıoğlu, Bahtiyar Özgür; Tekin, Bayram (Springer Science and Business Media LLC, 2008-01-01)
We obtain the static spherically symmetric solutions of a class of gravitational models whose additions to the General Relativity (GR) action forbid Ricci-flat, in particular, Schwarzschild geometries. These theories are selected to maintain the (first) derivative order of the Einstein equations in Schwarzschild gauge. Generically, the solutions exhibit both horizons and a singularity at the origin, except for one model that forbids spherical symmetry altogether. Extensions to arbitrary dimension with a cos...
DERELI, T; MUKHERJEE, M; TUCKER, RW (IOP Publishing, 1988-01-01)
A set of symmetric, traceless, divergence-free differential forms, Weyl covariant under a conformal scaling of a (pseudo-)Riemannian metric, is constructed in 4n-1 dimensions.
