A Statistical Approach to Multifield Inflation: Many-field Perturbations Beyond Slow Roll
Liam McAllister, Sébastien Renaux-Petel, Gang Xu
We study multifield contributions to the scalar power spectrum in an ensemble of six-field inflationary models obtained in string theory. We identify examples in which inflation oc…
Universality in D-brane Inflation
Nishant Agarwal, Rachel Bean, Liam McAllister +1
We study the six-field dynamics of D3-brane inflation for a general scalar potential on the conifold, finding simple, universal behavior. We numerically evolve the equations of mot…
Oscillations in the CMB from Axion Monodromy Inflation
Raphael Flauger, Liam McAllister, Enrico Pajer +2
We study the CMB observables in axion monodromy inflation. These well-motivated scenarios for inflation in string theory have monomial potentials over super-Planckian field ranges,…
Dynamical Threshold Enhancement and Resummation in Drell-Yan Production
Thomas Becher, Matthias Neubert, Gang Xu
Partonic cross sections for the production of massive objects in hadronic collisions receive large corrections when the invariant mass of the initial-state partons is just above th…
