B_{c} absorption cross sections by nucleons

The cross sections of $B_{c}$\ absorption by nucleons are calculated in meson-baryon exchange model using hadronic Lagrangian based on SU(4)/SU(5) flavor symmetries. The values of different coupling constants used in the model are obtained from vecto

The cross sections of $B_{c}$\ absorption by $\pi $ mesons are calculated using hadronic Lagrangian based on SU(5) flavor symmetry. Calculated cross sections are found to be in range 2 to 7 mb and 0.2 to 2 mb for the processes $B_{c}^{+}\pi \rightarr

A Simple Five-Dimensional Wave Equation for a Dirac Particle

Autor: Redington, N., Lodhi, M. A. K.

Publikováno v: J.Math.Phys.48:022303,2007

A first-order relativistic wave equation is constructed in five dimensions. Its solutions are eight-component spinors, which are interpreted as single-particle fermion wave functions in four-dimensional spacetime. Use of a ``cylinder condition'' (the

$B_c$ mesons in a Bethe-Salpeter model

Autor: El-Hady, A. Abd, Lodhi, M. A. K., Vary, J. P.

Publikováno v: Phys.Rev. D59 (1999) 094001

We apply our Bethe-Salpeter model for mesons to the $B_c$ family with parameters fixed in our previous investigation. We evaluate the mass of the pseudo-scalar $B_c$ meson as 6.356 GeV/$c^2$ and 6.380 GeV/$c^2$ and the lifetime as 0.47 ps and 0.46 ps
