Dispersive Bounds on The Shape Of Lambda_b to Lambda_c l {\bar ν_l} Formfactors

Debrupa Chakraverty, Triptesh De, Binayak Dutta-Roy +1

We derive a theoretically allowed domain for the charge radius $\rho$ and curvature $c$ of the Isgur-Wise function describing the decay ${\Lambda }_b\to {\Lambda }_{c}l{\bar{\nu }}_l$. Our method uses cro…
