Radiative Semileptonic Decays of Beautiful Hadrons

Federico Cima, Michele Papucci

In soft kinematics, radiative semileptonic form factors for beautiful hadron decays are completely fixed by non-radiative Isgur-Wise functions and magnetic dipole moments.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

In the soft and sub-leading soft regions, all the form factors are fully determined in terms of non-radiative Isgur-Wise functions and the magnetic dipole moments of the heavy hadrons.

C2weakest assumption

That the HQET symmetries remain valid and that the soft-region approximations capture the dominant contributions for the kinematics accessible at Belle II and LHCb.

C3one line summary

Within HQET, radiative semileptonic decay form factors for Lambda(b) to Lambda(c) and B to D(*) transitions are fully determined by non-radiative Isgur-Wise functions and heavy-hadron magnetic dipole moments in soft and sub-leading soft regions.
