QCD Crossover Transfer Functions for Scalar-Induced Gravitational Waves in the PTA Band
Gabriele Franciolini, Xavier Pritchard, Yuichiro Tada
Pulsar timing array (PTA) collaborations have reported evidence for a stochastic gravitational wave (GW) background in the nHz band. Should scalar-induced GWs, sourced at second or…

Bumpy inflation from explosive particle production
Kaloian D. Lozanov, Xavier Pritchard, Misao Sasaki
We present a first-principles derivation of an effective inflaton potential with a bumpy feature. We consider the coupling of a spectator field χto the inflaton ϕsuch that χis mass…
