Search for massive, long-lived particles in events with displaced vertices and displaced muons in collisions at TeV with the ATLAS experiment
ATLAS Collaboration
A search is presented for massive long-lived particles in events featuring at least one displaced vertex and at least one displaced muon, using proton-proton collision data collect…

Quantum state tomography, entanglement detection and Bell violation prospects in weak decays of massive particles
Rachel Ashby-Pickering, Alan J. Barr, Agnieszka Wierzchucka
A rather general method for determining the spin density matrix of a multi-particle system from angular decay data is presented. The method is based on a Bloch parameterisation of…

Search for low-mass dijet resonances using trigger-level jets with the ATLAS detector in collisions at TeV
ATLAS Collaboration
Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large Hadron Collider can be statistically limited by the bandwidth available to inclusive single-…
