Phenomenological Study of Strong Decays of Heavy Hadrons in Heavy Quark Effective Theory

TL;DR

This paper applies heavy quark effective theory using tensor formalism to analyze strong decays of heavy hadrons, comparing predictions with experiments and exploring applications to strange mesons.

Contribution

It introduces the use of tensor formalism in HQET for decay analysis and predicts unmeasured decay rates using spin-flavor symmetry.

Findings

Good agreement with experimental decay rate ratios for B and D mesons.

Encouraging results for strange meson decay predictions.

Predictions for unmeasured decay rates based on symmetry considerations.

Abstract

The application of the tensor formalism of the heavy quark effective theory (HQET) at leading order to strong decays of heavy hadrons is presented. Comparisons between experimental and theoretical predictions of ratios of decay rates for B mesons, D mesons and kaons are given. The application of HQET to strange mesons presents some encouraging results. The spin-flavor symmetry is used to predict some decay rates that have not yet been measured.
