Precision phenomenology of the PDF-BSM interplay
… unanswered. In this context, the high energy physics community looks for physics beyond the SM (BSM). One way to conduct these searches is by studying subtle deviations of our theoretical predictions from the observed experimental values. In this context, as it reaches unprecedented levels of …

Novel Networks in Collider Searches for New Physics
Beyond-Standard Model (BSM) physics searches at the LHC are limited by the amount of information available to distinguish a new physics process from its backgrounds. Analyses apply a range of classification algorithms to obtain sensitivity to rare signals, but are challenged to obtain enough …

Parton Distributions in Beyond the Standard Model Theories
… that the Standard Model (SM) of particle physics is complete; however, this can bias studies of beyond the Standard Model (BSM) physics if these SM-like PDFs are used in these analyses. It is important to quantify the extent to which this occurs, in order to avoid making incorrect …

Needles in the Quantum Haystack: CMS Anomaly Detection with Normalizing Flows
… for particles beyond the Standard Model (BSM) have yielded little in the realm of new physics discoveries. A number of research efforts have adopted new anomaly detection strategies which utilize density estimation algorithms based on unsupervised and semi-supervised machine learning. …

PHENOMENOLOGY OF THE STANDARD MODEL AND BEYOND
While the Standard Model (SM) of particle physics is the most precise theory everdiscovered, it is known to be incomplete. The SM cannot account for the observed Dark Matter (DM) in the universe or that the neutrinos have masses. Furthermore, theoretical puzzles such as the matter-antimatter …

Through Iron & Ice: Searching for Sterile Neutrinos at the IceCube Neutrino Observatory
… most promising portal for Beyond Standard Model (BSM) physics, and neutrinos have already provided fruitful surprises. A number of neutrino experiments in the last three decades have observed anomalous oscillation signals consistent with a mass-squared splitting of Δ𝑚2 ∼ 1 eV^2, motivating the …

Precision QCD and effective field theories with machine learning
… as one the best descriptions of fundamental physics we have and the quest for its falsification has led to it being tested to an unprecedented degree. Despite its flawless performance, there are many theoretical and phenomenological indications that the SM cannot be a complete description of …

Search for new hadronically decaying resonances with masses down to 20 GeV in pp collisions using the ATLAS Detector at the Large Hadron Collider
Many proposed models of physics beyond the Standard Model of particle physics (BSM) predict new resonances. Thus, a single experimental search for such new resonances can probe a multitude of BSM models. In particular, searches for resonances decaying into hadrons can probe for any resonances that …
