The Large Hadron electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) energy and intensity frontier particle physics. Exploiting recovery technology, it collides a novel, intense beam with proton or ion from High Luminosity--Large (HL-LHC). accelerator interaction region are for concurrent electron-proton proton-proton operation. This report represents an update Conceptual Design Report (CDR) LHeC, published in 2012. It comprises new results on parton...
A bstract The addition of d = 5 operators to the Seesaw model leads Dimension-5 Portal. Here, two new provide interactions for heavy sterile neutrinos. In particular, Higgs boson can have a large branching ratio into neutrinos, meaning that these states be searched at LHC. Moreover, neutrinos now decay dominantly light and photons. If are long-lived, then searches delayed, non-pointing photons constrain model. this work, we carry out detailed recast an ATLAS search such displaced photons,...
A bstract The Dimension-5 Seesaw Portal is a Type-I model extended by d = 5 operators involving the sterile neutrino states, leading to new interactions between all neutrinos and Standard Model neutral bosons. In this work we focus primarily on implications of these at GeV-scale. particular, recalculate heavy full decay width, up three-body decays. We also review bounds dipole operator, revisit LEP constraints its coefficient. Finally, turn pair production from Higgs decays, where former are...
The search strategy or the discovery of new effects for heavy neutrinos often rely on their different decay channels to detectable particles. In particular, in this work we study a Majorana neutrino with interactions obtained from an effective general theory modeling physics at scale $\mathrm{\ensuremath{\Lambda}}$. results are because they based and not specific models. We interested relatively light-heavy neutrinos, masses lower than $W$ mass (${m}_{N}<{m}_{W}$). This range simplifies by...
