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 ...

Non-factorisable effects in the decays B ¯ s 0 → D s + π − $$ {\overline{B}}_s^0\to {D}_s^{+}{\pi}^{-} $$ and B ¯ 0 → D + K − $$ {\overline{B}}^0\to {D}^{+}{K}^{-} $$ from LCSR

Journal of High Energy Physics, 2023
In light of the current discrepancies between the recent predictions based on QCD factorisation (QCDF) and the experimental data for several non-leptonic colour-allowed two-body B-meson decays, we obtain new determinations of the non-factorisable soft ...

Vectorlike Confinement at the LHC [PDF]

, 2010
We argue for the plausibility of a broad class of vectorlike confining gauge theories at the TeV scale which interact with the Standard Model predominantly via gauge interactions.

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

A guide to diagnosing colored resonances at hadron colliders

Journal of High Energy Physics, 2023
We present a comprehensive study on how to distinguish the properties of heavy dijet resonances at hadron colliders. A variety of spins, chiral couplings, charges, and QCD color representations are considered.

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 ...

QCD universality recovered via the Total Available Quadri‐Scalar [PDF]

, 2002
After presenting a brief review of the phenomenology of the Leading Effect, we define a new variable, the “Total Available Quadri‐Scalar” (ATOT) and propose it as the invariant quantity effectively available for the production of the multihadronic final ...

Constructivist Grounded Theory or Interpretive Phenomenology? Methodological Choices Within Specific Study Contexts

International Journal of Qualitative Methods, 2022
Constructivist research methodologies are useful in discerning meanings of experience to subsequently inform and improve healthcare practice. For researchers who philosophically align with the constructivist paradigm, numerous methodologies are available

Study of Bs⟶ϕℓ+ℓ− Decays in the PQCD Factorization Approach with Lattice QCD Input

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
In this paper, we studied systematically the semileptonic decays Bs⟶ϕl+l− with l− = (e−, μ−, τ−) by using the perturbative QCD (PQCD) and the “PQCD+Lattice” factorization approach, respectively. We first evaluated all relevant form factors Fi(q2) in the low‐q2 region using the PQCD approach, and we also took the available lattice QCD results at the ...

GlueX: The Search for Gluonic Excitations at Jefferson Laboratory [PDF]

, 2005
One of the unanswered and most fundamental questions in physics regards the nature of the confinement mechanism of quarks and gluons in quantum chromodynamics (QCD). Exotic hybrid mesons manifest gluonic degrees of freedom and their detailed spectroscopy
