Dynamical tachyonic AdS/QCD and information entropy
Physics Letters B, 2018 The configurational entropy setup is employed to study dynamical tachyonic holographic AdS/QCD models. The phenomenology of light-flavour mesonic states is then corroborated by the Shannon's information.

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

Instantons and the Large N_c Limit of QCD [PDF]
, 2002 We summarize our current understanding of instantons in the large N_c limit of QCD. We also present some recent results from simulations of the instanton liquid in QCD for N_c>3.Comment: 10 pages; talk given at the Workshop on the Phenomenology of Large

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 ...

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 ...

Infrared structure of SU(N) × U(1) gauge theory to three loops
Journal of High Energy Physics, 2020 We study the infrared (IR) structure of SU(N ) × U(1) (QCD × QED) gauge theory with n f quarks and n l leptons within the framework of perturbation theory.

The q T and ∆ϕ spectra in W and Z production at the LHC at N3LL′+N2LO
Journal of High Energy Physics, 2021 The production of weak gauge bosons, W ± and Z, are at the core of the LHC precision measurement program. Their transverse momentum spectra as well as their pairwise ratios are key theoretical inputs to many high-precision analyses, ranging from the W ...

Compatibility of a model for the QCD-Pomeron and chiral-symmetry breaking phenomenologies [PDF]
, 1996 The phenomenology of a QCD-Pomeron model based on the exchange of a pair of non-perturbative gluons, i.e. gluon fields with a finite correlation length in the vacuum, is studied in comparison with the phenomenology of QCD chiral symmetry breaking, based ...
