Anomaly detection for resonant new physics with machine learning

J Collins, K Howe, B Nachman - Physical review letters, 2018 - APS
Despite extensive theoretical motivation for physics beyond the standard model (BSM) of
particle physics, searches at the Large Hadron Collider have found no significant evidence …

Extending the search for new resonances with machine learning

JH Collins, K Howe, B Nachman - Physical Review D, 2019 - APS
The oldest and most robust technique to search for new particles is to look for “bumps” in
invariant mass spectra over smoothly falling backgrounds. We present a new extension of …

Dark matter interpretation of the neutron decay anomaly

B Fornal, B Grinstein - Physical review letters, 2018 - APS
There is a long-standing discrepancy between the neutron lifetime measured in beam and
bottle experiments. We propose to explain this anomaly by a dark decay channel for the …

Emerging jets

P Schwaller, D Stolarski, A Weiler - Journal of High Energy Physics, 2015 - Springer
A bstract In this work, we propose a novel search strategy for new physics at the LHC that
utilizes calorimeter jets that (i) are composed dominantly of displaced tracks and (ii) have …

A search for pair-produced resonances in four-jet final states at with the ATLAS detector

M Aaboud, G Aad, B Abbott, O Abdinov… - The European Physical …, 2018 - Springer
A search for massive coloured resonances which are pair-produced and decay into two jets
is presented. The analysis uses 36.7 fb^-1-1 of ss= 13 TeV pp collision data recorded by the …

Status of R-parity violating SUSY

A Choudhury, A Mondal, S Mondal - The European Physical Journal …, 2024 - Springer
In this article, we discuss various phenomenological implications of possible R-parity
violating (RPV) supersymmetric scenarios. In this context, the implications of both bilinear …

Automating the ABCD method with machine learning

G Kasieczka, B Nachman, MD Schwartz, D Shih - Physical Review D, 2021 - APS
The ABCD method is one of the most widely used data-driven background estimation
techniques in high energy physics. Cuts on two statistically independent classifiers separate …

Search for resonant and nonresonant production of pairs of dijet resonances in proton-proton collisions at = 13 TeV

CMS collaboration - arXiv preprint arXiv:2206.09997, 2022 - arxiv.org
A search for pairs of dijet resonances with the same mass is conducted in final states with at
least four jets. Results are presented separately for the case where the four jet production …

ΔACP within the Standard Model and beyond

M Chala, A Lenz, AV Rusov, J Scholtz - Journal of High Energy Physics, 2019 - Springer
A bstract In light of the recent LHCb observation of CP violation in the charm sector, we
review standard model (SM) predictions in the charm sector and in particular for ΔA CP. We …
