Holomorphic field theories and higher algebra
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Higher-order QCD corrections to hadronic τ decays from Padé approximants
Journal of High Energy Physics, 2018 Perturbative QCD corrections to hadronic τ decays and e + e − annihilation into hadrons below charm are obtained from the Adler function, which at present is known in the chiral limit to five-loop accuracy.

Structure‐Function Relationships of Biomass‐Derived Materials for Zinc Metal Protection
Advanced Science, Volume 12, Issue 34, September 11, 2025.This review analyses the mechanism of zinc anode degradation, focuses on the protective roles of the four major functional groups of carboxyl, amino, hydroxyl, and sulfonic acid groups in biomass materials, reveals the structure‐function relationship and synergistic effects of functional groups, and looks forward to the challenges and directions of ...

Quarkonium Spectroscopy and Perturbative QCD: A New Perspective [PDF]
, 2001 We study the energy spectrum of bottomonium in perturbative QCD, taking $\als(M_Z)=0.1181 \pm 0.0020$ as input and fixing $m_b^{\bar{\rm MS}}(m_b^{\bar{\rm MS}})$ on the $\Upsilon(1S)$ mass.

Heavy quark fragmentation in e + e − collisions to NNLO+NNLL accuracy in perturbative QCD
Journal of High Energy PhysicsFragmentation of heavy quarks into heavy-flavoured hadrons receives both perturbative and non-perturbative contributions. We consider perturbative QCD corrections to heavy quark production in e + e − collisions to next-to-next-to-leading order accuracy ...

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

APPROACHING THE FINAL STATE IN PERTURBATIVE QCD [PDF]
International Journal of Modern Physics A, 2003 Infrared safe differential cross-sections, such as event shape distributions, can be measured over wide kinematic ranges, from regions where fixed order calculations are adequate to regions where nonperturbative dynamics dominate. Such observables provide an ideal laboratory for the study of the transition between weak and strong coupling in quantum ...

On the Possibility of a Strong First-order Phase Transition in Neutron Stars
The Astrophysical JournalWhether cold dense quantum chromodynamics (QCD) matter undergoes a strong first-order phase transition remains an open question. In nature, neutron stars provide the most direct probe of cold dense QCD matter. Theoretically, chiral effective field theory

Sterile neutrino dark matter: impact of active-neutrino opacities
Journal of High Energy Physics, 2020 The resonant production of keV sterile-neutrino dark matter mainly takes place during the QCD epoch of the early universe. It has been argued that it could be strongly affected by the opacities (or damping rates) of active neutrinos, which receive non ...
