b-quark decay in the collinear approximation
نویسنده
چکیده
The semileptonic decay of a b-quark, b → clν, is considered in the relativistic limit where the decay products are approximately collinear. Analytic results for the double differential lepton energy distributions are given for finite charm-quark mass. Their use for the fast simulation of isolated lepton backgrounds from heavy quark decays is discussed.

In this research, we are going to study the QCD penguin structure and calculate the second order approximation. The amplitude of decays related to QCD penguin in the quark model up to the first and second orders were calculated. We calculated the amplitude of QCD penguin on lowest order of αs for the first order of the decay processes b→qkg→qkqiqj and for the second order of the decay processes...
متن کاملEffective Hamiltonian of Electroweak Penguin for Hadronic b Quark Decays
In this research we work with the effective Hamiltonian and the quark model. We investigate the decay rates of matter-antimatter of quark. We describe the effective Hamiltonian theory and apply this theory to the calculation of current-current ( ), QCD penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. The gluonic penguin structure of hadronic decays is studied thro...

I study bottom quark fragmentation in the Standard Model Higgs decay H → b ¯ b, within the framework of perturbative fragmentation functions. I resum large collinear logarithms ln(m 2 H /m 2 b) in the next-to-leading logarithmic (NLL) approximation, using the DGLAP evolution equations. Soft contributions to the MS coefficient function and to the initial condition of the perturbative fragmentati...
