Rare B->K*l(+)l(-) decay in light cone QCD

We investigate the transition form factors for the B-->K*l(+)l(-) (l = mu, tau) decay in light cone QCD. It is found that the light cone and three-point QCD sum rule analyses for some of the form factors for the decay B-->K*l(+)l(-) lead to absolutely different q(2) dependence. The invariant dilepton mass distributions for the B-->K*mu(+)mu(-) and B-->K*tau(+)tau(-) decays and final lepton longitudinal polarization asymmetry, which includes both short-and long-distance contributions, are also calculated.


Rare B->K*l(+)l(-) decay, two Higgs doublet model, and light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa; Özpineci, Altuğ (1997-10-02)
The decay width, forward-backward asymmetry and lepton longitudinal and transversal polarization for the exclusive B --> K* l(+)l(-) decay in a two Higgs doublet model are computed. It is shown that all these quantities are very effective tools for establishing new physics. (C) 1997 Elsevier Science B.V.
Light cone QCD sum rule analysis of B->Kl(+)l(-) decay
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (1997-05-08)
We calculate the transition formfactors for the B --> Kl(+)l(-) decay in the framework of the light cone QCD sum rules. The invariant dilepton mass distribution and the final lepton longitudinal polarization asymmetry are investigated. The comparison analysis of our results with traditional sum rules method predictions on the formfactors is performed. (C) 1997 Elsevier Science B.V.
Chaos from massive deformations of Yang-Mills matrix models
Başkan, K.; Kürkcüoğlu, Seçkin; Oktay, O.; Taşcı, Cankut (Springer Science and Business Media LLC, 2020-10-01)
We focus on an SU(N) Yang-Mills gauge theory in 0 + 1-dimensions with the same matrix content as the bosonic part of the BFSS matrix model, but with mass deformation terms breaking the global SO(9) symmetry of the latter to SO(5) x SO(3) x Z(2). Introducing an ansatz configuration involving fuzzy four and two spheres with collective time dependence, we examine the chaotic dynamics in a family of effective Lagrangians obtained by tracing over the aforementioned ansatz configurations at the matrix levels N = ...
Magnetic dipole moments of the negative parity J(PC)=2(--) mesons in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (2018-04-18)
Magnetic dipole moments of the negative parity light and heavy tensor mesons are calculated within the light cone QCD sum rules method. The results are compared with the positive parity counterparts of the corresponding tensor mesons. The results of the analysis show that the magnetic dipole moments of the negative parity light mesons are smaller compared to those of the positive parity mesons. Contrary to the light meson case, magnetic dipole moments of the negative parity heavy mesons are larger than the ...
Magnetic moment of the rho meson in QCD light cone sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2003-09-01)
The magnetic moment mu of the rho meson is studied in QCD light cone sum rules, and it is found that mu=(2.3+/-0.5), in units of e/2m(rho). A comparison of our result on the magnetic moment of the rho meson with the predictions of the other approaches is presented.
