Electroweak radiative corrections in precision LHC measurements of W±/Z0+jets
Nuclear Physics B, 2022 We calculate the fiducial and differential W±/Z0+jet(s) production cross-sections in the presence of electroweak (EW) corrections through virtual loop contributions to the matrix elements (MEs) of the processes and real partonic cascade emissions.

Two‐to‐Two Processes at an Electron‐Muon Collider
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Based on a recent proposal to build an electron‐muon collider, we study two‐to‐two production processes e−μ+⟶ff¯, γγ that originate from dimension 6 and 8 operators. We compare the sensitivity to those effective couplings obtained at the collider with that of low energy measurements of μ⟶eγ, μ⟶ee¯e, and μ⟶e conversion that have recently been reported ...

Studying Same‐Sign Top Pair Production through Top‐Higgs FCNC Interactions at the HL‐LHC
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We investigate the potential of the HL‐LHC for discovering new physics effects via the same‐sign top pair signatures. We focus on the semileptonic (electron and muon) decay of the top quarks and study the reach for a simplified model approach where top quark flavor changing could occur through a neutral scalar exchange.

PARTON SHOWERS AND MULTIJET EVENTS [PDF]
Fundamental and Applied Aspects of Modern Physics, 2001 A Monte-Carlo event-generator has been developed which is dedicated to simulate electron-positron annihilations. Especially a new approach for the combination of matrix elements and parton showers ensures the independence of the hadronization parameters from the CMS energy.

Comments on a new 'full colour' parton shower
, 2020 A new parton shower algorithm has been presented with the claim of providing soft-gluon resummation at `full colour' (arXiv:2001.11492). In this paper we show that the algorithm does not succeed in this goal.

Strangeness Enhancement at LHC Energies Using the Thermal Model and EPOSLHC Event Generator
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The strangeness enhancement signature of QGP formation at LHC energies is carefully tackled in the present study. Based on HRG, the particle ratios of mainly strange and multistrange particles are studied at energies from lower s~0.001 up to 13 TeV. The strangeness enhancement clearly appeared at more high energies, and the ratios are confronted to the

On the Interpretation of Nonresonant Phenomena at Colliders
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 With null results in resonance searches at the LHC, the physics potential focus is now shifting towards the interpretation of nonresonant phenomena. An example of such shift is the increased popularity of the EFT programme. We can embark on such programme owing to the good integrated luminosity and an excellent understanding of the detectors, which ...

LHC Signals of the Next‐to‐Lightest Scalar Higgs State of the NMSSM in the 4τ Decay Channel
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We study the a1a1 and Za1 decay channels of the next‐to‐lightest CP‐even Higgs boson h2 of the NMSSM at the LHC, where the h2 is produced in gluon fusion. It is found that while the h2 discovery is impossible through the latter channel, the former one in the 4τ final state is a promising channel to discover the h2 with masses up to around 250 GeV at ...
