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 ...

Next-to-leading-power kinematic corrections to DVCS: a scalar target
Journal of High Energy Physics, 2023 Using the recent results on the contributions of descendants of the leading twist operators to the operator product expansion of two electromagnetic currents we derive explicit expressions for the kinematic finite-t and target mass corrections to the ...

The photon energy spectrum in B → X s γ at N3LL′
Journal of High Energy Physics, 2023 We present predictions for the photon energy spectrum in inclusive B → X s γ decays mediated by the electromagnetic penguin operator O 7 to N3LL′. We use soft-collinear effective theory (SCET) to resum the singular contributions in the peak region at ...

Gravitational transition form factors of N → ∆ via QCD light-cone sum rules
Journal of High Energy Physics, 2023 We present the first direct calculation on the gravitational form factors (GFFs) of the N → ∆ transition using an analytic method, the QCD light-cone sum rules. The matrix element of the quark part of the energy momentum tensor current sandwiched between

A possible subthreshold pole in S 11 channel from πN Roy-Steiner equation analyses
Journal of High Energy Physics, 2022 The hyperbolic version of Roy-Steiner equation describing low energy πN scatterings, with larger analyticity domain in the complex s plane is solved. The numerical results on phase shifts of low partial waves are in agreement with that of Hoferichter et ...

Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach
Contributions to Plasma Physics, EarlyView.ABSTRACT We derive a generalized Beth–Uhlenbeck formula for the entropy of a dense fermion system with strong two‐particle correlations, including scattering states and bound states. We work within the Φ‐derivable approach to the thermodynamic potential.

On-shelļ methods for perturbative QCD [PDF]
, 2006 We present new on-shell techniques for the calculation of colour ordered helicity amplitudes in QCD. We review the methods of on-shell recursion and the MHV rules before applying them to tree-level processes within the Standard Model.

Angular coefficients from interpretable machine learning with symbolic regression
Journal of High Energy PhysicsWe explore the use of symbolic regression to derive compact analytical expressions for angular observables relevant to electroweak boson production at the Large Hadron Collider (LHC).
