Generalising Holographic Superconductors
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper we propose a generalised holographic framework to describe superconductors. We first unify the description of s‐, p‐, and d‐wave superconductors in a way that can be easily promoted to higher spin. Using a semianalytical procedure to compute the superconductor properties, we are able to further generalise the geometric description of the ...

Standard Model prediction of the B c lifetime
Journal of High Energy Physics, 2021 Applying an operator product expansion approach we update the Standard Model prediction of the B c lifetime from over 20 years ago. The non-perturbative velocity expansion is carried out up to third order in the relative velocity of the heavy quarks. The

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 ...

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.

Colour and logarithmic accuracy in final-state parton showers
Journal of High Energy Physics, 2021 Standard dipole parton showers are known to yield incorrect subleading-colour contributions to the leading (double) logarithmic terms for a variety of observables. In this work, concentrating on final-state showers, we present two simple, computationally

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

Global analysis of the Sivers functions at NLO+NNLL in QCD
Journal of High Energy Physics, 2021 We perform global fit to the quark Sivers function within the transverse momentum dependent (TMD) factorization formalism in QCD. We simultaneously fit Sivers asymmetry data from Semi-Inclusive Deep Inelastic Scattering (SIDIS) at COMPASS, HERMES, and ...

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

PHENOMENOLOGY FROM LATTICE QCD [PDF]
Lepton-Photon 01, 2002 I review two subject in which lattice simulations are making, or can make in the future, a significant contribution to particle physics phenomenology. The first subject is the evaluation of quantities which enter into the determination of the vertex A of the unitarity triangle from experimental measurements of decay rates and mixing amplitudes.

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 ...
