Analysis of the semileptonic ${\Lambda }_b\to \Lambda {\ell }^{+}{\ell }^{-}$ transition in topcolor-assisted technicolor (TC2) model

K. Azizi, S. Kartal, A. T. Olgun +1

We comparatively analyze the flavor changing neutral current process of the ${\Lambda }_b\to \Lambda {\ell }^{+}{\ell }^{-}$ in the standard model as well as topcolor-assisted technicolor model us…
