Delaying the waterfall transition in warm hybrid inflation
Mar Bastero-Gil, Arjun Berera, Thomas P. Metcalf +1
We analyze the dynamics and observational predictions of supersymmetric hybrid inflation in the warm regime, where dissipative effects are mediated by the waterfall fields and thei…
Determination of from a lattice-QCD calculation of the semileptonic form factor with physical quark masses
A. Bazavov, C. Bernard, C. Bouchard +21
We calculate the kaon semileptonic form factor from lattice QCD, working, for the first time, at the physical light-quark masses. We use gauge configurations generated by…
N and hidden-charm resonances with heavy-quark spin symmetry
Olena Romanets, Carmen Garcia-Recio, Lorenzo Luis Salcedo +2
We study N and hidden-charm baryon resonances that are generated dynamically from the s-wave interaction of pseudoscalar and vector mesons with and baryons. We…
FDR, an easier way to NNLO calculations: a two-loop case study
Alice Maria Donati, Roberto Pittau
In this paper we illustrate the simplifications produced by FDR in NNLO computations. We show with an explicit example that - due to its four-dimensionality - FDR does not require…
The Polyakov loop in various representations in the confined phase of QCD
E. Megias, E. Ruiz Arriola, L. L. Salcedo
We analyze the expectation value of the Polyakov loop in the fundamental and higher representations in the confined phase of QCD. We discuss a hadronic like representation, and fin…
LHC bounds on Lepton Number Violation mediated by doubly and singly-charged scalars
Francisco del Aguila, Mikael Chala
The only possible doubly-charged scalar decays into two Standard Model particles are into pairs of same-sign charged leptons, H…
