Discovery and Exclusion Prospects for Staus Produced by Heavy Higgs Boson Decays at the LHC
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In a previous work, we developed a search strategy for staus produced by the decay of the heavy CP‐even Higgs boson H within the context of the large tanβ regime of the minimal supersymmetric standard model (MSSM) in a scenario of large stau mixing. Here, we study the performance of such search strategy by confronting it with the complementary mixing ...

Framing energetic top-quark pair production at the LHC
Journal of High Energy Physics, 2021 Top-quark pair production is central to many facets of LHC physics. At leading order, the top and anti-top are produced in a back-to-back topology, however this topology accounts only for a minority of the events with TeV-scale momentum transfer that ...

On the Impact of the LHC Run 2 Data on General Composite Higgs Scenarios
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We study the impact of Run 2 LHC data on general composite Higgs scenarios, where nonlinear effects, mixing with additional scalars, and new fermionic degrees of freedom could simultaneously contribute to the modification of Higgs properties. We obtain new experimental limits on the scale of compositeness, the mixing with singlets and doublets with the

The high-energy limit of perturbative QCD: Theory and phenomenology
, 2022 After a brief introduction of formal and phenomenological progresses in the study of the high-energy limit of perturbative QCD, we present arguments supporting the statement that the inclusive emission of Higgs bosons or heavy-flavored hadrons acts as ...

Some remarks on anthropic approaches to the strong CP problem
Journal of High Energy Physics, 2018 The peculiar value of θ is a challenge to the notion of an anthropic landscape. We briefly review the possibility that a suitable axion might arise from an anthropic requirement of dark matter.

QCD Effective Locality: A Theoretical and Phenomenological Review [PDF]
Universe, 2021 About ten years ago, the use of standard functional manipulations was demonstrated to imply an unexpected property satisfied by the fermionic Green’s functions of QCD and dubbed Effective Locality. This feature of QCD is non-perturbative, as it results from a full gauge invariant integration of the gluonic degrees of freedom.

Pinning down the large-x gluon with NNLO top-quark pair differential distributions
Journal of High Energy Physics, 2017 Top-quark pair production at the LHC is directly sensitive to the gluon PDF at large x. While total cross-section data is already included in several PDF determinations, differential distributions are not, because the corresponding NNLO calculations have

Journal of High Energy Physics, 2020 We discuss the role of intrinsic charm (IC) in the nucleon for forward production of c-quark (or c ¯ $$ \overline{c} $$ -antiquark) in proton-proton collisions for low and high energies.
