Finding excesses in model parameter space
Kierthika Chathirathas, Torben Ferber, Felix Kahlhoefer +1
Simulation-based inference (SBI) makes it possible to infer the parameters of a model from high-dimensional low-level features of the observed events. In this work we show how this…
Reconstructing axion-like particles from beam dumps with simulation-based inference
Alessandro Morandini, Torben Ferber, Felix Kahlhoefer
Axion-like particles (ALPs) that decay into photon pairs pose a challenge for experiments that rely on the construction of a decay vertex in order to search for long-lived particle…
Searching for dark radiation at the LHC
Elias Bernreuther, Felix Kahlhoefer, Michele Lucente +1
In this work we explore the intriguing connections between searches for long-lived particles (LLPs) at the LHC and early universe cosmology. We study the non-thermal production of…
Forecasting dark showers at Belle II
Elias Bernreuther, Kai Böse, Torben Ferber +4
Dark showers from strongly interacting dark sectors that confine at the GeV scale can give rise to novel signatures at colliders. In this work, we study the sensitivity of…
What's Anomalous in LHC Jets?
Thorsten Buss, Barry M. Dillon, Thorben Finke +5
Searches for anomalies are a significant motivation for the LHC and help define key analysis steps, including triggers. We discuss specific examples how LHC anomalies can be define…
Autoencoders for unsupervised anomaly detection in high energy physics
Thorben Finke, Michael Krämer, Alessandro Morandini +2
Autoencoders are widely used in machine learning applications, in particular for anomaly detection. Hence, they have been introduced in high energy physics as a promising tool for…
Nonparametric Density Estimation from Markov Chains
Andrea De Simone, Alessandro Morandini
We introduce a new nonparametric density estimator inspired by Markov Chains, and generalizing the well-known Kernel Density Estimator (KDE). Our estimator presents several benefit…
Les Houches 2019 Physics at TeV Colliders: New Physics Working Group Report
G. Brooijmans, A. Buckley, S. Caron +87
This report presents the activities of the `New Physics' working group for the `Physics at TeV Colliders' workshop (Les Houches, France, 10--28 June, 2019). These activities includ…
Composite 2HDM with singlets: a viable dark matter scenario
Alessandro Davoli, Andrea De Simone, David Marzocca +1
We study the non-minimal composite Higgs model with global symmetry broken to . The model results in a composite Two-Higgs doublet m…
Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider
Juliette Alimena, James Beacham, Martino Borsato +198
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Had…
LHC Phenomenology of Dark Matter with a Color-Octet Partner
Alessandro Davoli, Andrea De Simone, Thomas Jacques +1
Colored dark sectors where the dark matter particle is accompanied by colored partners have recently attracted theoretical and phenomenological interest. We explore the possibility…
