Decays of Charmed Vector Mesons --- eta-pi^0 mixing as an origin of isospin non-conservation ---

TL;DR

This paper investigates the decay processes of charmed vector mesons, predicting decay widths and exploring isospin non-conservation via eta-pi^0 mixing, providing insights into meson decay mechanisms.

Contribution

It offers new predictions for D^{*0} decay widths and examines isospin non-conservation effects in D_s^{*+} decays through eta-pi^0 mixing.

Findings

Predicted the full-width of D^{*0} assuming isospin symmetry.

Analyzed isospin non-conserving decay D_s^{*+} --> D_s^+ pi^0 via eta-pi^0 mixing.

Provided theoretical insights into meson decay mechanisms.

Abstract

Pion emitting decays and radiative ones of D^{*+,0} and D_s^{*+} are studied. As the result, the full-width of D^{*0} is predicted, by assuming the isospin symmetry. In addition, the isospin non-conserving D_s^{*+} --> D_s^+ pi^0 decay is investigated under the assumption that it proceeds through the eta-pi^0 mixing.
