Collider Bias

open access: yesJAMA, 2022
This JAMA Guide to Statistics and Methods describes collider bias, illustrates examples in directed acyclic graphs, and explains how it can threaten the internal validity of a study and the accurate estimation of causal relationships in randomized clinical trials and observational studies.

Collider bias undermines our understanding of COVID-19 disease risk and severity

open access: yesNature Communications, 2020
Numerous observational studies have attempted to identify risk factors for infection with SARS-CoV-2 and COVID-19 disease outcomes. Studies have used datasets sampled from patients admitted to hospital, people tested for active infection, or people who ...

SuperKEKB collider [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2018
SuperKEKB, a 7 GeV electron - 4 GeV positron double-ring collider, is constructed by upgrading KEKB in order to seek new physics beyond the Standard Model. The design luminosity of SuperKEKB is 8 x 10^35 /cm^2 /s - 40 times higher than that achieved by KEKB.

Towards a muon collider [PDF]

open access: yesThe European Physical Journal C, 2023
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated ...

First Direct Observation of Collider Neutrinos with FASER at the LHC. [PDF]

open access: yesPhysical Review Letters, 2023
We report the first direct observation of neutrino interactions at a particle collider experiment. Neutrino candidate events are identified in a 13.6 TeV center-of-mass energy pp collision dataset of 35.4  fb^{-1} using the active electronic components ...

Observation of Collider Muon Neutrinos with the SND@LHC Experiment. [PDF]

open access: yesPhysical Review Letters, 2023
We report the direct observation of muon neutrino interactions with the SND@LHC detector at the Large Hadron Collider. A dataset of proton-proton collisions at sqrt[s]=13.6  TeV collected by SND@LHC in 2022 is used, corresponding to an integrated ...
