On the trivalent junction of three non-tachyonic heterotic string theories

Yuji Tachikawa · 2026

Recently, Altavista, Anastasi, Angius and Uranga discussed a method to construct junctions and bouquets of different perturbative string theories. Following this analysis, we here argue that three non…

Inferring viscoplastic models from velocity fields: a physics-informed neural network approach

Martin Lardy, Sham Tlili, Simon Gsell · 2025

Fluid-like materials are ubiquitous, spanning from living biological tissues to geological formations, and across scales ranging from micrometers to kilometers. Inferring their rheological properties …

BRST Symmetry and the Convolutional Double Copy

Mahdi Godazgar, C.N. Pope, A. Saha, Haoyu Zhang · 2022

Motivated by the results of Anastasiou et al., we consider the convolutional double copy for BRST and anti-BRST covariant formulations of gravitational and gauge theories in more detail. We give a gen…

Fluid-structure interaction simulation of floating structures interacting with complex, large-scale ocean waves and atmospheric turbulence

Antoni Calderer, Xin Guo, Lian Shen, Fotis Sotiropoulos · 2016

We develop a numerical method for simulating coupled interactions of complex floating structures with large-scale ocean waves and atmospheric turbulence. We employ an efficient large-scale model to de…

RG improved Higgs boson production to N$^3$LO in QCD

Taushif Ahmed, Goutam Das, M. C. Kumar, Narayan Rana, V. Ravindran · 2015

The recent result on the third order correction to the Higgs boson production through gluon fusion by Anastasiou et al. [1] not only provides a precise prediction with reduced scale uncertainties for …

Critical Remarks on Finsler Modifications of Gravity and Cosmology by Zhe Chang and Xin Li

Sergiu I. Vacaru · 2010

I do not agree with the authors of papers arXiv:0806.2184 and arXiv:0901.1023v1 (published in Phys. Lett., respectively, B668 (2008) 453 and B676 (2009) 173). They consider that \textit{"In Finsler ma…

N=4 Super-Yang-Mills Theory, QCD and Collider Physics

Z. Bern, L.J. Dixon, D.A. Kosower · 2004

We review how (dimensionally regulated) scattering amplitudes in N=4 super-Yang-Mills theory provide a useful testing ground for perturbative QCD calculations relevant to collider physics, as well as …

Higgs boson production at hadron colliders: differential cross sections through next-to-next-to-leading order

Charalampos Anastasiou, Kirill Melnikov, Frank Petriello · 2004

We present a calculation of the fully differential cross section for Higgs boson production in the gluon fusion channel through next-to-next-to-leading order in perturbative QCD. We apply the method i…

Two-Loop Helicity Amplitudes for Quark-Gluon Scattering in QCD and Gluino-Gluon Scattering in Supersymmetric Yang-Mills Theory

Z. Bern, A. De Freitas, L. Dixon · 2003

We present the two-loop QCD helicity amplitudes for quark-gluon scattering, and for quark-antiquark annihilation into two gluons. These amplitudes are relevant for next-to-next-to-leading order correc…
