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.

Opportunities for new physics searches with heavy ions at colliders (2023)
Journal Article
d’Enterria, D., Drewes, M., Giammanco, A., Hajer, J., Bratkovskaya, E., Bruce, R., …Upreti, A. (2023). Opportunities for new physics searches with heavy ions at colliders. 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...

Early-Universe Model Building (2023)
Working Paper
Asadi, P., Bansal, S., Berlin, A., Co, R. T., Croon, D., Cui, Y., …Yu, H. (2023). Early-Universe Model Building

Theoretical investigations into the evolution of the early universe are an essential part of particle physics that allow us to identify viable extensions to the Standard Model as well as motivated parameter space that can be probed by various experim... Read More about Early-Universe Model Building.
