Double-real-virtual and double-virtual-real corrections to the three-loop thrust soft function

open access: yesJournal of High Energy Physics, 2022
We compute the O $$ \mathcal{O} $$ ( α s 3 $$ {\alpha}_s^3 $$ ) double-real-virtual (RRV) and double-virtual-real (VVR) soft contributions to the thrust/zero-jettiness event shape.

Higher order perturbative QCD calculation of jet cross sections ine + e − annihilation

open access: yesZeitschrift für Physik C Particles and Fields, 1982
We present in detail the analytic calculation of the Sterman-Weinberg type 3-jet cross section to order αs2 The fit to recent PLUTO data gives in the\({MS}\) scheme αs which corresponds to Λ=0.24 GeV in the 1-loop approximation.

Probing large-order perturbative expansions in lattice gauge theories with fermions [PDF]

open access: yes, 2019
Many perturbative expansions in quantum field theories are believed to be plagued by factorial divergences. This can be seen as a reflection of the fact that an all-order perturbative computation cannot give a complete description of the theory, as it

NLO EW and QCD corrections to polarised same-sign WW scattering at the LHC

open access: yesJournal of High Energy Physics
We present the first calculation of same-sign WW scattering at the LHC in the fully leptonic decay channel including the modelling of polarisation for intermediate electroweak bosons and radiative corrections up to NLO EW+QCD accuracy.

A Feynman integral depending on two elliptic curves

open access: yesJournal of High Energy Physics, 2022
We study a two-loop four-point function with one internal mass. This Feynman integral is one of the simplest Feynman integrals depending on two elliptic curves. We transform the associated differential equation into an ε-form. We study the entries of the

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Finite scattering amplitudes in field theory [PDF]

open access: yes, 2007
In this thesis we explore the infrared problem perturbatively in massless field theory. We review the current conventional methods and theorems that are applied in the calculation of QCD jet observables and then discuss the formulation of an alternative ...

Explainable AI-assisted optimization for Feynman integral reduction

open access: yesJournal of High Energy Physics
We present a novel approach to optimizing the reduction of Feynman integrals using integration-by-parts identities. By developing a priority function through the FunSearch algorithm, which combines large language models and genetic algorithms, we achieve

Baikov representations, intersection theory, and canonical Feynman integrals

open access: yesJournal of High Energy Physics, 2022
The method of canonical differential equations is an important tool in the calculation of Feynman integrals in quantum field theories. It has been realized that the canonical bases are closely related to d-dimensional d log-form integrands. In this work,

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
