Slow-down of expanding bubbles in the early Universe
Nabeen Bhusal, Simone Blasi, Thomas Konstandin +2
We study slow-down effects for bubbles formed in a cosmological first-order phase transition (PT) focusing on deflagrations and hybrids, where the bubble wall is preceded by a shoc…
High-Frequency Gravitational Waves from Phase Transitions in Nascent Neutron Stars
Katarina Bleau, Joachim Kopp, Jiheon Lee +1
Tentative evidence suggests that the cores of massive neutron stars consist of deconfined quark matter. We argue that the formation of such a quark matter core during a galactic su…
Finite-temperature bubble nucleation with shifting scale hierarchies
Maciej Kierkla, Philipp Schicho, Bogumila Swiezewska +2
Focusing on supercooled phase transitions in models with classical scale symmetry, we formulate a state-of-the art framework for computing the bubble-nucleation rate, accounting fo…
Theories and Experiments for Testable Baryogenesis Mechanisms: A Snowmass White Paper
J. L. Barrow, Leah Broussard, James M. Cline +16
The baryon asymmetry of the Universe is one of the central motivations to expect physics beyond the Standard Model. In this Snowmass white paper, we review the challenges and oppor…
Early-Universe Model Building
Pouya Asadi, Saurabh Bansal, Asher Berlin +37
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 w…
Preheating from target space curvature and unitarity violation: Analysis in field space
Yohei Ema, Ryusuke Jinno, Kazunori Nakayama +1
We study particle production and unitarity violation caused by a curved target space right after inflation. We use the inflaton field value instead of cosmic time as the time varia…
Source terms for electroweak baryogenesis in the vev-insertion approximation beyond leading order
Marieke Postma, Jorinde van de Vis
In electroweak baryogenesis the baryon asymmetry of the universe is created during the electroweak phase transition. The quantum transport equations governing the dynamics of the p…
The role of leptons in electroweak baryogenesis
Jordy de Vries, Marieke Postma, Jorinde van de Vis
We investigate the role of leptons in electroweak baryogenesis by studying a relatively simple framework inspired by effective field theory that satisfies all Sakharov conditions.…
