TheΛ b →Λ c decay form factors

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Combining Drell-Yan type overlap integrals with results from the heavy quark effective theory, we calculate the six form factors for semileptonicΛ b →Λ c decays and predict the differential decay rate as well as the asymmetry parameter. SemileptonicΛ c →Λ s decays and the electromagnetic form factors of heavy Λ's are briefly discussed.
