Static linear response of hot and dense QCD matter to electromagnetic fields: Leading hard and soft QCD corrections
Osvaldo Ferreira, Eduardo S. Fraga, Tyler Gorda +3
We compute the static electromagnetic susceptibilities of a hot and dense quark-gluon plasma using perturbative Quantum Chromodynamics (QCD). Our evaluation includes the leading $\…
Semi-analytic bounds on axion-like-particle supernovae emission
Ana Luisa Foguel, Eduardo S. Fraga
Core-collapse supernovae provide natural laboratories for the production of new light particles. In particular, axion-like particles (ALPs) can be constrained via SN1987A cooling a…
Signatures from pion condensation and lepton flavor asymmetries in the cosmological gravitational wave background
Osvaldo Ferreira, Eduardo S. Fraga, Jürgen Schaffner-Bielich
Large lepton flavor asymmetries at the QCD epoch could generate a pion condensation phase in the early Universe. For large enough tau lepton flavor asymmetries, the speed of sound…
