Phase transitions and baryogenesis from decays (2017)
Journal Article
Shuve, B., & Tamarit, C. (2017). Phase transitions and baryogenesis from decays. Journal of High Energy Physics, 2017(10), Article 122. https://doi.org/10.1007/jhep10%282017%29122

We study scenarios in which the baryon asymmetry is generated from the decay of a particle whose mass originates from the spontaneous breakdown of a symmetry. This is realized in many models, including low-scale leptogenesis and theories with classic... Read More about Phase transitions and baryogenesis from decays.

Convexity, gauge-dependence and tunneling rates (2016)
Journal Article
Plascencia, A. D., & Tamarit, C. (2016). Convexity, gauge-dependence and tunneling rates. Journal of High Energy Physics, 2016(10), Article 99. https://doi.org/10.1007/jhep10%282016%29099

We clarify issues of convexity, gauge-dependence and radiative corrections in relation to tunneling rates. Despite the gauge dependence of the effective action at zero and finite temperature, it is shown that tunneling and nucleation rates remain ind...

Higgs portal valleys, stability and inflation (2015)
Journal Article
Ballesteros, G., & Tamarit, C. (2015). Higgs portal valleys, stability and inflation. Journal of High Energy Physics, 2015(9), Article 210. https://doi.org/10.1007/jhep09%282015%29210

The measured values of the Higgs and top quark masses imply that the Standard Model potential is very likely to be unstable at large Higgs values. This is particularly problematic during inflation, which sources large perturbations of the Higgs. The... Read More about Higgs portal valleys, stability and inflation.
