TLDR
Horizontal branch stars evolution based on mass distributions from comparison with giant branch, investigating evolutionary track characteristics during core helium burning was studied in this paper, where the authors proposed a model of the evolution of horizontal branch stars.Abstract:

Convective Overshooting in Horizontal Branch Stars
TL;DR: In this paper, the evolution of horizontal branch stars up to the starting of the thermally pulsing regime of the He-burning shell is investigated with the aid of a non-local treatment of the core convection.

Current problems on horizontal branch stars
TL;DR: In this article, the influence of Main Sequence stellar rotation on horizontal branch stars and RR Lyrae pulsational properties is studied, and it is shown that the main sequence stellar rotation has a strong influence on the properties of branch stars.

Comparison of the Asteroseismic Mass Scale of Red Clump Giants with Photometric Mass Estimates
TL;DR: Asteroseismology can provide joint constraints on masses and radii of individual stars as mentioned in this paper, but it is difficult to test for helium core-burning red-clump (RC) giants because of the lack of fundamental calibrators.
