Is B→Xsγ equal to b→sγ? Spectator contributions to rare inclusive B decays
With perturbation quark-gluon hadron attenuation photon spectral lines the photon energy
2014/12/23
In B→Xsγ, there are perturbative QCD corrections at order αs not only to the single quark line process b→sγ but also coming from a set of diagrams where the weak interaction vertex involves a gluon wh...
Stability of fragments and study of participant-spectator matter at peak center-of-mass energy
center-of-mass energy participant-spectator matter
2011/7/20
We simulate the central reactions of nearly symmetric, and asymmetric systems, for the energies at which the maximum production of IMFs occurs (E$_{c.m.}^{peak}$).This study is carried out by using ha...
The role of Spectator Fragments at an electron Ion collider
Spectator Fragments electron Ion collider
2010/3/16
Efficient detection of spectator fragments is key to the main topics at an electron-ion collider (eIC). Any process which leads to emission of fragments or $\gamma$'s breaks coherence in diffractive p...
Weighted azimuthal asymmetries in a diquark spectator model
azimuthal asymmetries diquark spectator model
2010/3/16
We analytically calculate weighted azimuthal asymmetries in semi-inclusive lepton-nucleon deep-inelastic scattering and Drell-Yan processes, using transverse-momentum-dependent partonic densities obta...
Induced Fractional Zero-Point Angular Momentum for Charged Particles of the Bohm-Aharonov System by means of a "Spectator" Magnetic Field
Fractional Zero-Point Angular Momentum Particles of the Bohm-Aharonov System Spectator
2010/4/8
An induced fractional zero-point angular momentum of charged particles by the Bohm-Aharonov (B-A) vector potential is realized via a modified combined trap. It explores a "spectator" mechanism in this...
