Tree-level splitting amplitudes for a gluon into four collinear partons
We compute in conventional dimensional regularisation the tree-level splitting amplitudes for a gluon parent which splits into four collinear partons. This is part of the universal infrared behaviour of the QCD scattering amplitudes at next-to-next-to ...

Understanding forward B hadron production
The LHCb collaboration has recently performed a measurement of the production rate of inclusive B hadron production (pp → BX) at both 7 and 13 TeV centre-of-mass (CoM) energies.

Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach
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.

Large effects from small QCD instantons: making soft bombs at hadron colliders
It is a common belief that the last missing piece of the Standard Model of particles physics was found with the discovery of the Higgs boson at the Large Hadron Collider.

The DNA of Calabi–Yau Hypersurfaces
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Analytic results for Sudakov form factors in QCD
Sudakov form factors appear ubiquitously in factorized cross sections where they allow one to resum large logarithms to all orders in perturbation theory.

An Overview of Scale Invariance in Proton Structure With Holographic Insights
The concept of self‐similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).

Prompt hadroproduction of η c (1S, 2S) in the k T -factorization approach
In this work, we present a thorough analysis of η c (1S, 2S) quarkonia hadroproduction in k ⊥-factorisation in the framework of the light-front potential approach for the quarkonium wave function. The off-shell matrix elements for the g * g * η c (1S, 2S)

Infrared structure of SU(N) × U(1) gauge theory to three loops
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.

Complementary Probes of the Dimension‐6 Operator via Gravitational Waves and Multi‐Higgs Production
We investigate the phenomenological consequences of a dimension‐6 operator H†H3/Λ2, Λ is the effective scale at which new physics takes over, which modifies the scalar potential of the standard model and can induce a strong first‐order electroweak phase transition (SFOEWPT). We estimate the lower limit on the effective scale Λ to be 515 GeV from the di‐
