Next-to-leading-power kinematic corrections to DVCS: a scalar target

open access: yesJournal 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′

open access: yesJournal 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 ...

A new suite of Lund-tree observables to resolve jets

open access: yesJournal of High Energy Physics
We introduce a class of collider observables, named Lund-Tree Shapes (LTS), defined from declustering trees originating from the Lund jet plane representation of the QCD radiation pattern in multi-jet scattering processes. At the differential level, they

The DNA of Calabi–Yau Hypersurfaces

open access: yesFortschritte der Physik, Volume 74, Issue 2, February 2026.
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.

Quark polarization and transverse momentum effects on double quarkonium production in hadronic collisions

open access: yesJournal of High Energy Physics
We investigate the inclusive production of double quarkonia (J/ψ, ψ(2S), Υ mesons) in polarized hadron-hadron collisions, considering the kinematic configuration where the transverse momentum of each pair of bound states is much smaller than its ...

An Overview of Scale Invariance in Proton Structure With Holographic Insights

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
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).

Complementary Probes of the Dimension‐6 Operator via Gravitational Waves and Multi‐Higgs Production

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
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‐

Angular coefficients from interpretable machine learning with symbolic regression

open access: yesJournal of High Energy Physics
We 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).

Kinked tracks from Σ + baryons as a probe of light quark polarizations

open access: yesJournal of High Energy Physics, 2023
Jets initiated by energetic quarks carry in an obvious way approximate information about the original quark energy and momentum. In a less obvious way, they also carry information about the quark polarization.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.
