The impact of quark masses on pQCD thermodynamics

, 2016
We present results for several thermodynamic quantities within the next-to-leading order calculation of the thermodynamic potential in perturbative QCD at finite temperature and chemical potential including non-vanishing quark masses.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Double neutral-current corrections to NLO electroweak leptonic cross sections

Journal of High Energy Physics
We present a method for improving next-to-leading order electroweak (EW) predictions for lepton-scattering processes by consistently including double neutral-current corrections arising from vector-boson-fusion topologies, which are formally of higher ...

Two-loop mixed QCD-EW corrections to q q ¯ $$ q\overline{q} $$ → Hg, qg → Hq, and q ¯ g $$ \overline{q}g $$ → H q ¯ $$ H\overline{q} $$

Journal of High Energy Physics, 2022
We compute the two-loop mixed QCD-Electroweak corrections to q q ¯ $$ q\overline{q} $$ → Hg and its crossed channels qg → Hq, q ¯ g $$ \overline{q}g $$ → H q ¯ $$ H\overline{q} $$ , limiting ourselves to the contribution of light virtual quarks.

Numerical evaluation of two-loop integrals with pySecDec

, 2017
We describe the program pySecDec, which factorises endpoint singularities from multi-dimensional parameter integrals and can serve to calculate integrals occurring in higher order perturbative calculations numerically. We focus on the new features and on

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Two-loop mixed QCD-electroweak amplitudes for Z+jet production at the LHC: bosonic corrections

Journal of High Energy Physics
We present a calculation of the bosonic contribution to the two-loop mixed QCD-electroweak scattering amplitudes for Z-boson production in association with one hard jet at hadron colliders.

Three-loop master integrals for the Higgs boson self-energy with internal top-quarks and W-bosons

Journal of High Energy Physics, 2022
We consider the full set of master integrals with internal top-and W-propagators contributing to the three-loop Higgs self-energy diagrams of order O $$ \mathcal{O} $$ (α 2 α s ).

Resummation Effects in Vector-Boson and Higgs Associated Production [PDF]

, 2012
Fixed-order QCD radiative corrections to the vector-boson and Higgs associated production channels, pp -> VH (V=W, Z), at hadron colliders are well understood.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
