Using Forward-Backward Drell-Yan Asymmetry in PDF Determinations

Autor: Fiaschi, Juri, Accomando, Elena, Hautmann, Francesco, Moretti, Stefano

We study the impact of the inclusion of Neutral Current (NC) DY data from LHC mapped in the Forward-Backward Asymmetry ($A_{\rm FB}$) observable on PDF uncertainties, using the open source platform \texttt{xFitter}. We find that $A_{\rm FB}$ enables

We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of a wide range of theories that address unsolved fundamental mysteries

Constraining PDFs from neutral current Drell-Yan measurements and effects of resummation in slepton pair production

Autor: Fiaschi, Juri, Accomando, Elena, Hautmann, Francesco, Klasen, Michael, Moretti, Stefano

The high statistics that will be collected during the LHC Run-II (and beyond) open the path to precision measurements at the TeV scale, where the PDFs will play a crucial role in BSM searches. In the di-lepton final state accurate measurements of the

Extra Higgs Boson and $Z'$ as Portals to Signatures of Heavy Neutrinos at the LHC

Autor: Accomando, Elena, Rose, Luigi Delle, Moretti, Stefano, Olaiya, Emmanuel, Shepherd-Themistocleous, Claire H.

In this paper, we discuss the potential of observing heavy neutrino ($\nu_h$) signatures of a $U(1)_{B-L}$ enlarged Standard Model (SM) encompassing three heavy Majorana neutrinos alongside the known light neutrino states at the Large Hadron Collider

Real and virtual photons effects in di-lepton production at the LHC

Autor: Accomando, Elena, Fiaschi, Juri, Hautmann, Francesco, Moretti, Stefano, Shepherd-Themistocleous, Claire H.

We show the SM prediction of di-lepton production at the LHC where to the usual Drell-Yan production we add the contribution from Photon-Initiated processes. We discuss the effects of the inclusion of photon interactions in the high invariant mass re
