INFORMATION AND PARTICLE PHYSICS [PDF]
Modern Physics Letters A, 2011 Information measures for relativistic quantum spinors are constructed to satisfy various postulated properties such as normalization invariance and positivity. Those measures are then used to motivate generalized Lagrangians meant to probe shorter distance physics within the maximum uncertainty framework.

On non-factorisable contributions to t-channel single-top production
Journal of High Energy Physics, 2021 We compute the non-factorisable contribution to the two-loop helicity amplitude for t-channel single-top production, the last missing piece of the two-loop virtual corrections to this process.

Probing the gluon plasma with charm balance functions
European Physical Journal C: Particles and Fields, 2021 Recent theoretical explanations for how hydrodynamic-like flow can build up quickly in small collision systems (hydrodynamization) has led to a microscopic picture of flow building up in a gluon-dominated phase before chemical equilibrium between quarks ...

Journal of High Energy Physics, 2023 We present a novel construction for a Higgs-VEV sensitive (HVS) operator, which can be used as a trigger operator in cosmic selection models for the electroweak hierarchy problem.

Towards the ultimate differential SMEFT analysis
Journal of High Energy Physics, 2020 We obtain SMEFT bounds using an approach that utilises the complete multi-dimensional differential information of a process. This approach is based on the fact that at a given EFT order, the full angular distribution in the most important electroweak ...

Unified Experiment Monitoring [PDF]
EPJ Web of ConferencesThe Unified Experiment Monitoring (UEM) is the project in WLCG with the objective to harmonize the WLCG job accounting reports across the LHC experiments, in order to provide aggregated reports of the compute capacity used by WLCG as a function of time ...

European Physical Journal C: Particles and Fields, 2023 Inspired by the brilliant prospects of the ongoing B meson experiments, the hadronic charmless B $${\rightarrow }$$ → SS decays are studied by considering the next-to-leading (NLO) contributions with the QCD factorization approach, where S denotes the ...

Particle physics and cosmology [PDF]
General Relativity and Gravitation, 1995 ABSTRACTThe agreement between the observed light element abundances and calculations of homogeneous cosmological nucleosynthesis constrains inhomogenequs models, and suggests that most of the matter in the Universe is invisible Dark Matter. This could be in the form of neutrinos, lightest supersymmetric particles (LSPs) or axions.
