A guide to diagnosing colored resonances at hadron colliders

Journal of High Energy Physics, 2023
We present a comprehensive study on how to distinguish the properties of heavy dijet resonances at hadron colliders. A variety of spins, chiral couplings, charges, and QCD color representations are considered.

Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Gauge‐Singlet Vector‐Like Fermion Dark Matter, LHC Diphoton Rate, and Direct Detection

Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017
We study a gauge‐singlet vector‐like fermion hidden sector dark matter model, in which the communication between the dark matter and the visible standard model sector is via the Higgs‐portal scalar‐Higgs mixing and also via a hidden sector scalar with loop‐level couplings to two gluons and also to two hypercharge gauge bosons induced by a vector‐like ...

Hunting and identifying coloured resonances in four top events with machine learning

Journal of High Energy Physics
We study prospects to search for pair or singly produced colour octet or colour sextet scalars which decay into two top quarks at the LHC. We focus on the same-sign lepton final state.

Engendering carcerality: An introduction

Gender &History, Volume 36, Issue 3, Page 807-823, October 2024.
Abstract Reflecting the carceral turn in scholarship, this introduction to a special issue on engendering carcerality explores the difference that gender makes in the history of the carceral in its various forms over time and space. It considers the multiple meanings and spaces of imprisonment, surveillance, and confinement; incarceration of mothers ...

Phenomenological Hints from a Class of String Motivated Model Constructions

Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
We use string theory constructions towards the generalisation of the supersymmetric standard model of strong and electroweak interactions. Properties of the models depend crucially on the location of fields in extradimensional compact space. This allows us to extract some generic lessons for the phenomenological properties of the low energy effective ...

Faking ZZZ vertices at the LHC

Journal of High Energy Physics
Searches for anomalous neutral triple gauge boson couplings (NTGCs) provide important tests for the gauge structure of the standard model. At the LHC, NTGCs are searched for via the process pp → ZZ → 4l, where the two Z-bosons are on-shell. In this paper,

Solar disk integration polarimeter: An automated disk‐integration full‐Stokes‐vector solar feed for the Potsdam Echelle Polarimetric and Spectroscopic Instrument spectrograph

Astronomische Nachrichten, Volume 345, Issue 6-7, July-August 2024.
Abstract We introduce a new solar feed for the PEPSI nighttime spectrograph of the LBT. It enables spectroscopy of the Sun‐as‐a‐star in circular polarization (CP) and linear polarization (LP) with a spectral resolution of 250,000 (≈0.025Å or 600ms−1$$ 600\kern0.1em \mathrm{m}\kern0.1em {\mathrm{s}}^{-1} $$) for the wavelength range 383–907 nm.

Status of LHC Searches for SUSY without R‐Parity

Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
In this contribution we briefly review the status of current searches for supersymmetry at the Large Hadron Collider, focusing especially on viable sub‐TeV colored superpartners which can appear in nonstandard scenarios. The presented material covers mostly signals that do not crucially rely on the presence of large missing transverse momentum, with ...

Revisiting μ-e conversion in R-parity violating SUSY

Journal of High Energy Physics
The μ-e conversion process is one of the most powerful ways to test lepton-flavor-violating (LFV) interactions involving charged leptons. The standard model with massive neutrinos predicts an extremely low rate for μ-e conversion, making this process an ...
