Journal of High Energy Physics, 2015 New pseudo-scalars, often called axion-like particles (ALPs), abound in model-building and are often associated with the breaking of a new symmetry. Traditional searches and indirect bounds are limited to light axions, typically in or below the KeV range for ALPs coupled to photons.

DELPHES 3: a modular framework for fast simulation of a generic collider experiment [PDF]
Journal of High Energy Physics, 2013 The version 3.0 of the Delphes fast-simulation is presented. The goal of Delphes is to allow the simulation of a multipurpose detector for phenomenological studies.

Selection bias due to conditioning on a collider
British medical journal, 2023 Effect estimates may be biased when the study design or the data analysis is conditional on a collider—a variable that is caused by two other variables. Causal directed acyclic graphs are a helpful tool to identify colliders that may introduce selection ...

New parton distributions for collider physics [PDF]
, 2010 We extract new parton distribution functions (PDFs) of the proton by global analysis of hard scattering data in the general-mass framework of perturbative quantum chromodynamics.

Parton distributions from high-precision collider data [PDF]
The European Physical Journal C, 2017 We present a new set of parton distributions, NNPDF3.1, which updates NNPDF3.0, the first global set of PDFs determined using a methodology validated by a closure test.

Healthcare utilization is a collider: an introduction to collider bias in EHR data reuse
J. Am. Medical Informatics Assoc., 2023 OBJECTIVES Collider bias is a common threat to internal validity in clinical research but is rarely mentioned in informatics education or literature. Conditioning on a collider, which is a variable that is the shared causal descendant of an exposure and ...

Multiloop corrections for collider processes using auxiliary mass flow [PDF]
Physical Review D, 2021 With a key improvement, the auxiliary mass flow method is now able to compute Feynman integrals encountered in cutting-edge collider processes. We have successfully applied it to compute some integrals involved in two-loop electroweak corrections to e+e−

Supergravity at colliders [PDF]
Physics Letters B, 2004 We consider supersymmetric theories where the gravitino is the lightest superparticle (LSP). Assuming that the long-lived next-to-lightest superparticle (NSP) is a charged slepton, we investigate two complementary ways to prove the existence of supergravity in nature.
