Fourth-generation standard model imprints in B-->K[script-l][script-l] decays with polarized K

Aqeel Ahmed, Ishtiaq Ahmed, M. Jamil Aslam, M. Junaid, M. Ali Paracha et al.
The implication of the fourth-generation quarks in the B-->K[script-l][script-l] ([script-l]=[mu],tau) decays when K meson is longitudinally or transversely polarized is presented herein. In this context, the dependence of the branching ratio with polarized K and the helicity fractions (f) of K meso ... [Phys. Rev. D 85, 034018 ] published .

Unified description of hadron-photon and hadron-meson scattering in the Dyson-Schwinger approach

Gernot Eichmann and Christian S. Fischer
We derive the expression for the nonperturbative coupling of a hadron to two external currents from its underlying structure in QCD. Microscopically, the action of each current is resolved to a coupling with dressed quarks. The Lorentz structure of the currents is arbitrary and thereby allows to des ... [Phys. Rev. D 85, 034015 ] published .

Analysis of B-->K*(-->Kpi)[mu][mu] in the higher kaon resonance region

Cai-Dian Lu and Wei Wang
We study the resonant contributions in the process of [overline B]-->Kpi[mu][mu] with the Kpi invariant mass square m[is-an-element-of][1,5] GeV. Width effects of the involved strange mesons, K(1410), K(1430), K(1430), K(1680), K(1780) and K(2045), are incorporated. In terms of helicity amplitudes, ... [Phys. Rev. D 85, 034014 ] published .

Analysis of B mixing angles in the presence of new physics and an update of B-->[overline K]K

Sebastien Descotes-Genon, Joaquim Matias, and Javier Virto
We discuss a simple approach to measure the weak mixing angles phi and phi of the B and B systems in the presence of New Physics. We present a new expression that allows one to measure directly phi if New Physics contributes significantly to the mixing only. We apply the method to specific penguin-m ... [Phys. Rev.

New approach to identifying boosted hadronically decaying particles using jet substructure in its center-of-mass frame

Chunhui Chen
In this paper, we introduce a new approach to study jet substructure in the center-of-mass frame of the jet. We demonstrate that it can be used to discriminate the boosted heavy particles from the QCD jets and the method is complementary to other jet substructure algorithms. Applications to searches ...

Isolating CP-violating gammaZZ coupling in ee-->gammaZ with transverse beam polarizations

B. Ananthanarayan, Sumit K. Garg, Monalisa Patra, and Saurabh D. Rindani
We revisit the process ee-->gammaZ at the ILC with transverse beam polarization in the presence of anomalous CP-violating gammaZZ coupling lambda and gammagammaZ coupling lambda. We point out that if the final-state spins are resolved, then it becomes possible to fingerprint the anomalous coupling R ... [Phys. Rev. D 85, 034006 ] published .

Electromagnetic properties of the neutrinos in gammap collision at the LHC

İ. Şahin
We have investigated nonstandard nu[overline nu ]gamma and nu[overline nu ]gammagamma couplings via nu[overline nu ] production in a gammap collision at the LHC. We obtain 95% confidence level bounds on nu[overline nu ]gamma and nu[overline nu ]gammagamma couplings by considering three differen ... [Phys. Rev. D 85, 033002 ] published .

Model dependence of the bremsstrahlung effects from the superluminal neutrino at OPERA

Fedor Bezrukov and Hyun Min Lee
We revisit the bremsstrahlung process of a superluminal neutrino motivated by OPERA results. From a careful analysis of the plane-wave solutions of the superluminal neutrino, we find that the squared matrix elements contain additional terms from Lorentz violation due to the modified spin sum for the ...

Form factors for semileptonic, nonleptonic, and rare B(B) meson decays

Mikhail A. Ivanov, Jurgen G. Korner, Sergey G. Kovalenko, Pietro Santorelli, and Gozyal G. Saidullaeva
We provide new values for the model parameters of the covariant constituent quark model (with built-in infrared confinement) in the meson sector by a fit to the leptonic decay constants and a number of electromagnetic decays. We then evaluate, in a parameter-free way, the form factors of the B(B)--> ... [Phys. Rev. D 85, 034004 ] published .

Transition radiation from the neutrino-photon interaction in matter

Juan Carlos D'Olivo and Jose Antonio Loza
We show that, because of their effective electromagnetic interaction in matter, transition radiation is emitted whenever neutrinos goes across the boundary between two media with different indices of refraction. This effect occurs in the context of the standard model and does not depend on any exoti ... [Phys. Rev. D 85, 011303 ] published .

Chiral particle decay of heavy-light mesons in a relativistic potential model

Takayuki Matsuki and Koichi Seo
Partial decay widths of the heavy-light mesons, D, D, B, and B, emitting one chiral particle (pi or K) are evaluated in the framework of a relativistic potential model. Decay amplitudes are calculated by keeping the Lorentz invariance as far as possible and use has been made of the Lorentz-boosted r ... [Phys. Rev. D 85, 014036 ] published .

pi-->gammagamma transition form factor within the light-front quark model

Chong-Chung Lih and Chao-Qiang Geng
The transition form factor of pi-->gammagamma is studied as a function of the momentum transfer Q within the light-front quark model (LFQM). Results are compared with the experimental data by the BABAR collaboration as well as other calculations based on the LFQM in the literature. It is shown that ... [Phys. Rev.

An SU(4) extrapolation of the chiral unitary theory in coupled channels done to study the scalar mesons in the charm sector is extended to produce results in finite volume. The theory in the infinite volume produces dynamically the D(2317) resonance by means of the coupled channels KD, etaD. Energy ... [Phys. Rev. D 85, 014027 ] published .
