abstract

Charm and bottom mesons and baryons are incorporated into a low energy chiral Lagrangian. Interactions of the heavy hadrons with light octet Goldstone bosons are studied in a framework which represents a synthesis of chiral perturbation theory and the heavy quark effective theory. The differential decay rate for the semileptonic process $\LBzero \to \Sigma_c^{++} + e^- + \bar{\nu}_e + \pi^-$ is calculated at the zero recoil point using this hybrid formalism.

  1. A Phenomenological Model of Mesons for Charged Current Weak Decays

    hep-ph 2026-05 unverdicted novelty 6.0 of 10

    A symmetry-guided phenomenological model organizes leading current-current operators for charged-current decays of heavy-light mesons and reproduces heavy-quark scaling relations for decay constants and form factors.

  2. Radiative Semileptonic Decays of Beautiful Hadrons

    hep-ph 2025-12 unverdicted novelty 6.0 of 10

    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 a...

  3. Chiral effective theory of scalar and vector diquarks revisited

    hep-ph 2024-11 conditional novelty 5.0 of 10

    A new term in the chiral diquark Lagrangian is shown to control the mass ordering of pseudoscalar diquarks and to set the threshold at which heavy-baryon decays turn off under chiral restoration.
