Role of Time‐Varying Magnetic Field on QGP Equation of State
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.The phase diagram of quantum chromodynamics (QCD) and its associated thermodynamic properties of quark‐gluon plasma (QGP) are studied in the presence of time‐dependent magnetic field. The study plays a pivotal role in the field of cosmology, astrophysics, and heavy‐ion collisions. In order to explore the structure of quark‐gluon plasma to deal with the

Top Quark Flavor Changing Couplings at a Muon Collider
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.

Journal of High Energy PhysicsMotivated by the recent measurements of CP violating effects in singly Cabibbo suppressed D 0 decays, we revisit the theoretical predictions of these channels. Using up-to-date values for the decay constants and form factors, we find already within naive

q‐Deformed Glueball Spectrum in AdS/QCD Correspondence
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.This work presents the application of the q‐algebra in the glueball spectrum. This algebra is implemented through Jackson’s derivatives in a Schrödinger‐like equation resulting from the gravity fluctuations around the braneworld scenario in five dimensions.

Non-factorisable contributions of strong-penguin operators in Λ b → Λℓ + ℓ − decays
Journal of High Energy PhysicsWe investigate for the first time a certain class of non-factorisable contributions of the four-quark operators O $$ \mathcal{O} $$ 3−6 in the weak effective Hamiltonian to the Λ b → Λℓ + ℓ − decay amplitude.

Parton distributions confront LHC Run II data: a quantitative appraisal
Journal of High Energy PhysicsWe present a systematic comparison of theoretical predictions and various high-precision experimental measurements, specifically of differential cross sections performed by the LHC run II for Drell-Yan gauge boson, top-quark pair, single-inclusive jet ...

On Drell-Yan production of scalar leptoquarks coupling to heavy-quark flavours
Journal of High Energy Physics, 2022 Given the hints of lepton-flavour non-universality in semi-leptonic B decays, leptoquark (LQ) models with sizeable couplings to heavy-quark flavours are enjoying a renaissance.

Drell-Yan production in third-generation gauge vector leptoquark models at NLO+PS in QCD
Journal of High Energy Physics, 2023 Motivated by the long-standing hints of lepton-flavour non-universality in the b → cℓν and b → sℓ + ℓ − channels, we study Drell-Yan ditau production at the Large Hadron Collider (LHC).

Measuring quantum discord at the LHC
Journal of High Energy PhysicsThere has been an increasing interest in exploring quantities associated with quantum information at colliders. We perform a detailed analysis describing how to measure the quantum discord in the top anti-top quantum state at the Large Hadron Collider ...

Local vs. nonlocal entanglement in top-quark pairs at the LHC
Journal of High Energy PhysicsWe show that the entanglement observed in top-antitop quark spin states at the LHC is local in the energy region close to the production threshold. In contrast, nonlocal entanglement is observed in the central boosted region defined by a top-quark pair ...
