ATLAS experiment

Precise timing detectors for the LHC experiments

by Panos Charitos, with contributions from Tommaso Tabarelli de Fatis, Lindsey Gray (CMS) and Ana Maria Henriques Correia, Laurent Serin (ATLAS)

 To meet the physics goals of the HL-LHC physics programme, ATLAS and CMS experiments have submitted proposals for timing detectors that will boost their physics reach.  

Heavy-ion collisions at Quark Matter 2018

by Panagiotis Charitos

CERN experiments present results from the study of lead-lead collisions at Quark Matter 2018.

New season starts for the LHC experiments

by Panos Charitos

Last April, the detectors of the Large Hadron Collider (LHC) witnessed their first collisions of 2017 with the machine reaching an outstanding performance. 

As the LHC experiments gather more data physics analysis can benefit from the development of novel machine learning tools. 

The exploitation of the LHC data is continuing successfully, with a wealth of new results presented at the Moriond 2018 conference,

In a recent publication, the ATLAS experiment measured the width of the top quark in a model-independent way and searched for contributions from new physics. 

Searching for leptoquarks at the LHC

by Panos Charitos

A recent “Cross Collider” meeting at CERN showed that the physics of leptoquarks remains a rapidly evolving field on both experimental and theoretical fronts.

The ATLAS collaboration has presented evidence of Higgs boson produced in association with top quarks, a rare process that provide new insight into the Higgs mechanism. 

Although the energy scale of New Physics might lie beyond current experiments' reach, the study of W and Z bosons and photons, through their self-interactions, can reveal hints of new physics at LHC energies and offer useful lessons for future high-energy colliders.

Colliding photons at the LHC!

by Panos Charitos

Image result for Colliding photons at the LHCLHC is the world’s most powerful collider not only for protons and lead ions but also for photon–photon allowing physicists to study this topic.
