BubbleDet: a Python package to compute functional determinants for bubble nucleation (2023)
Journal Article
Ekstedt, A., Gould, O., & Hirvonen, J. (2023). BubbleDet: a Python package to compute functional determinants for bubble nucleation. Journal of High Energy Physics, 2023(12), Article 56. https://doi.org/10.1007/jhep12%282023%29056

We present a Python package BubbleDet for computing one-loop functional determinants around spherically symmetric background fields. This gives the next-to-leading order correction to both the vacuum decay rate, at zero temperature, and to the bubble...

Higher orders for cosmological phase transitions: a global study in a Yukawa model (2023)
Journal Article
Gould, O., & Xie, C. (2023). Higher orders for cosmological phase transitions: a global study in a Yukawa model. Journal of High Energy Physics, 2023(12), Article 49. https://doi.org/10.1007/jhep12%282023%29049

We perform a state-of-the-art global study of the cosmological thermal histories of a simple Yukawa model, and find higher perturbative orders to be important for determining both the presence and strength of strong first-order phase transitions. Usi... Read More about Higher orders for cosmological phase transitions: a global study in a Yukawa model.

Journal of Physics G: Nuclear and Particle Physics, 50(5), Article 050501. https://doi.org/10.1088/1361-6471/acc197

Opportunities for searches for phenomena beyond the Standard Model (BSM) using heavy-ions beams at high energies are outlined. Different BSM searches proposed in the last years in collisions of heavy ions, mostly at the Large Hadron Collider, are sum...
