Robust anomaly detection for particle physics using multi-background representation learning

Machine Learning: Science and Technology
Anomaly, or out-of-distribution, detection is a promising tool for aiding discoveries of new particles or processes in particle physics. In this work, we identify and address two overlooked opportunities to improve anomaly detection (AD) for high-energy ...

Proton Stability and Light $Z^\prime$ Inspired by String Derived Models

, 2011
Proton stability is one of the most perplexing puzzles in particle physics. While the renormalizable Standard Model forbids proton decay mediating operators due to accidental global symmetries, many of its extensions introduce such dimension four, five ...

Anomalies in Particle Physics

Proceedings of 8th Symposium on Prospects in the Physics of Discrete Symmetries — PoS(DISCRETE2022)
I provide a (personal) review of the current hints for physics beyond the Standard Model, called ``anomalies'', obtained both at the intensity frontier (flavour and electroweak precision observables) and in direct LHC searches. This includes the deviations from the Standard Model predictions in semi-leptonic $B$ decays, the anomalous magnetic moment of

Investigation of Halogen Substitution Effects in π‐Conjugated Organic Ligands of Chiral Hybrid Perovskites on Their Chiroptical Activity

Advanced Functional Materials, EarlyView.
The role of novel thiophene‐based ligands with halogen substitutions in enhancing the chiroptical and optoelectronic properties of 2D chiral HOIPs has been investigated. By tailoring ligand design, enhanced CD and CPL properties are achieved, with improved CPL discrimination in photodetectors.

The EDGES 21 cm Anomaly and Properties of Dark Matter

, 2018
The recently claimed anomaly in the measurement of the 21 cm hydrogen absorption signal by EDGES at $z\sim 17$, if cosmological, requires the existence of new physics.

Dark matter for b → sμ + μ − anomaly in a gauged U(1) X model

Journal of High Energy Physics, 2018
We propose a new physics model which has a cold dark matter candidate and can explain the b → sμ + μ − anomaly at the same time. Our model includes a scalar quark q ˜ $$ \tilde{q} $$ and a scalar lepton ℓ ˜ $$ \tilde{\ell} $$ which are SU(2) L -doublet ...

Anomalies and the chiral magnetic effect in the Sakai-Sugimoto model

, 2009
In the chiral magnetic effect an imbalance in the number of left- and right-handed quarks gives rise to an electromagnetic current parallel to the magnetic field produced in noncentral heavy-ion collisions.
