Threshold resummation for semi-inclusive single-hadron production with effective field theory

Journal of High Energy Physics
Large double-logarithmic corrections are induced by soft gluon emissions near threshold in the semi-inclusive e + e − annihilation (SIA) distributions, and must be resummed to all-orders in perturbation theory for reliable theoretical predictions ...

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

Advances 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‐

Localization and Dualities in Three Dimensional Superconformal Field Theories [PDF]

, 2012
In this thesis we apply the technique of localization to three-dimensional N=2 superconformal field theories. We consider both theories which are exactly superconformal, and those which are believed to flow to nontrivial superconformal fixed points, for

Extraction of Effective Parameters From Transverse Momentum Spectra of Heavy Quarkonia in Proton–Proton Collisions at the LHC

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The effective string tension (κ) in the Schwinger mechanism and the effective temperature (T) in Bose–Einstein statistics are extracted from the transverse momentum (pT) spectra of heavy quarkonia produced in proton‐proton (p + p) collisions at the Large Hadron Collider (LHC).

Two loop vertices and tree level multicollinear limits in QCD [PDF]

, 2005
We present a summary of the methods required to solve loop-integrals and their reduction to Master Integrals. We then present the expansion in d = 4 - 2e of the Master Integrals required for the two loop massless vertex diagrams with three off-shell legs.

Superconducting multi-vortices and a novel BPS bound in chiral perturbation theory

Journal of High Energy Physics
We derive a novel BPS bound from chiral perturbation theory minimally coupled to electrodynamics at finite isospin chemical potential. At a critical value of the isospin chemical potential, a system of three first-order differential field equations ...

The Immune Microenvironment in Liver Cancer: From Analysis to Targeting

Advanced Science, Volume 12, Issue 47, December 18, 2025.
This review explores how smart nanomedicines overcome the immunosuppressive tumor microenvironment in liver cancer. It details targeted delivery strategies and immune reprogramming mechanisms, including remodeling abnormal physiology, modulating metabolism, and inducing immunogenic cell death. The article highlights the paradigm shift toward multimodal

Effective Meson Field Theory from QCD

, 2003
We give a simple and straightforward procedure of how to construct an effective meson Lagrangian from QCD Lagrangian. We integrate the methods of Gasser, Leutwyler, Alkofer and Reinhardt and use the derivative expansion scheme to derive the low energy effective Lagrangian for meson fields to $O(p^4)$.

Precision QCD and effective field theories with machine learning

, 2022
The Standard Model (SM) serves as one the best descriptions of fundamental physics we have and the quest for its falsification has led to it being tested to an unprecedented degree. Despite its flawless performance, there are many theoretical and phenomenological indications that the SM cannot be a complete description of nature; though, so far, no ...

Lignin as a Renewable Precursor for Carbon Quantum Dots: Synthesis, Doping Strategies, and Applications

Advanced Energy and Sustainability Research, Volume 6, Issue 12, December 2025.
Lignin‐derived carbon quantum dots are produced via hydrothermal doping with ethylenediamine, enhancing fluorescence, quantum yield, and tunable photoluminescence for diverse applications. These biocompatible nanomaterials enable safe use in bioimaging, sensing, and monitoring, offering optical stability under various conditions. Valorizing lignin from
