Baryon number freeze-out in the Standard Model, precisely
Cristina Benso, Dietrich Bödeker, Kohei Kamada +4
Weak sphaleron transitions turn a lepton asymmetry of the Standard Model plasma in the early Universe into a baryon asymmetry, conserving baryon-minus-lepton number and its i…
Theoretical uncertainties in reconstructing model parameters with gravitational waves from supercooled phase transitions
Maciej Kierkla, Marek Lewicki, Philipp Schicho +2
Future interferometers may detect a gravitational-wave (GW) signal from a cosmological first-order phase transition. Reconstructing the underlying particle-physics model from such…
A critical look at low-scale cosmological phase transitions in the PTA era
Simone Biondini, Philipp Schicho
Motivated by the recent evidence for a stochastic gravitational-wave (GW) background reported by pulsar timing array (PTA) collaborations, we perform a precision study of low-scale…
Higher-dimensional operators and Polyakov loop in hot Scalar QED from the heat kernel
Siddhartha Bandyopadhyay, Joydeep Chakrabortty, Debmalya Dey +2
Using the finite-temperature heat kernel method, we compute the gauge-invariant effective Lagrangian up to dimension-six for massive hot scalar QED. We propose two complementary me…
Matching higher-dimensional operators at finite temperature for general models
Fabio Bernardo, Romain Guillermo Reinle, Philipp Schicho
High-temperature dimensional reduction provides a systematic effective field theory framework for studying finite-temperature thermodynamics and cosmological phase transitions. Whi…
Finite-temperature operator basis on for SMEFT
Joydeep Chakrabortty, Bruno Siqueira Eduardo, Siddhartha Karmakar +1
We present the first complete non-redundant operator basis for the Standard Model Effective Field Theory (SMEFT) at finite temperature, using the imaginary-time formalism. By emplo…
