Targeting Multi-Loop Integrals with Neural Networks
Ramon Winterhalder, Vitaly Magerya, Emilio Villa +5
Numerical evaluations of Feynman integrals often proceed via a deformation of the integration contour into the complex plane. While valid contours are easy to construct, the numeri…
511 keV line constraints on feebly interacting particles from supernovae
Francesca Calore, Pierluca Carenza, Maurizio Giannotti +4
Feebly interacting particles with masses with O(10-100) MeV can be copiously produced by core-collapse supernovae (SNe). In this paper we consider the case of MeV-ish sterile neutr…
Phase structure of 2+1-flavour QCD and the magnetic equation of state
Fei Gao, Jan M. Pawlowski
We determine the chiral phase structure of -flavour QCD in dependence of temperature and the light flavour quark mass with Dyson-Schwinger equations. Specifically, we compute…
One-loop corrections to ALP couplings
J. Bonilla, I. Brivio, M. B. Gavela +1
We derive the one-loop contributions to ALP-SM effective couplings, including all finite corrections. The complete leading-order -- dimension five -- effective linear Lagrangian is…
Reconciling the FOPT and CIPT Predictions for the Hadronic Tau Decay Rate
Miguel A. Benitez-Rathgeb, Diogo Boito, Andre H. Hoang +1
In a recent work it was suggested that the discrepancy observed in the perturbation series behavior of the hadronic decay rate determined in the FOPT and CIPT approaches can be…
Searching for Charged Higgs Bosons via at Linear Colliders
Wei-Shu Hou, Rishabh Jain, Tanmoy Modak
We study a search for the charged Higgs boson via at the 500 GeV ILC. In a general two Higgs doublet model without symmetry, extra Yu…
