Sussex ATLAS group present at the International Conference on High Energy Physics (ICHEP)

Physicists from around the world will gather for the first *all-virtual* ICHEP conference, where a rich harvest of latest results from the Large Hadron Collider (LHC) experiments will be presented alongside the European Strategy Update and exciting events for the public.

The Sussex ATLAS group, led by Prof Antonella De Santo, have been working around the clock to analyse the latest proton-proton collision data collected by the ATLAS experiment to present to the community. These findings allow physicists to build a picture of the most fundamental particles and forces that make up our universe.

Among the many contributions, Sussex researcher Dr Tom Stevenson will be presenting the latest results for the searches for supersymmetric particles, hypothetical particles that may give a clue to the nature of dark matter and open doors to new physics!

Research fellow Dr Mark Sutton will be presenting the latest results on the internal structure of the proton, to help shed light on the fundamental structure of all the matter around us, and to provide accurate predictions of all the physics processes that are measured at the LHC, which may lead the way towards observing potential new physics.

PhD Student Mario Grandi will be presenting the design and performance of the ATLAS Inner Detector Trigger, which is key to selecting collisions used in analysis and searching for new physics, for which Sussex plays a key role in the experiment.

“I was very excited when I was told that I would be representing the ATLAS Collaboration at the ICHEP 2020 conference this year. ICHEP is one of the most prestigious conferences in the field of High Energy Physics, and I am honoured to be able to give a talk to show results of my own work. This is certainly one of the reasons I decided to do a PhD in particle physics!” said Mario.

PhD student Meirin Evans will be presenting the latest developments of the ATLAS Public Website, providing the public with access to descriptions of the ATLAS experiment, educational resources and updates such as news, briefings and blogs. The website has grown in popularity to now receive 30000 views per week! 

And finally Dr Kate Shaw will be presenting the latest ATLAS Open Data release and development, allowing the public and students to access collision data and search for fundamental particles such as the Higgs, or new particles such as dark matter from their own laptop.

Additionally, the Sussex ATLAS Top group are involved in probing in detail the interaction between some of the heavyweights of the Standard Model. The associated production of a top quark pair and a Z boson is a rare process involving some of the heaviest particles in nature, and it required the energy of the LHC be fully investigated. The result, presented at the ICHEP conference this week, features a leading contribution from Dr Tom Stevenson from Sussex, and it is summarised in a briefing co-authored by Prof Iacopo Vivarelli.

To complement the physics programme an outreach event will be showcasing Universal Science: an evening of presentations and open panel discussions where Dr Kate Shaw will be presenting ‘Strengthening physics through diversity” which can be watched live over YouTube, 5th August 7pm UK time.

Prof De Santo said: "I am always so very proud when the excellent work we do on the ATLAS experiment at Sussex gets showcased at international conferences, especially by early-career researchers. This year's bonanza of Sussex presenters at the most important worldwide conference for particle physics is a real moment for celebration, especially seeing how we are making key contributions to the advancement of scientific knowledge as well as to the global discourse on open science and the importance of equality and diversity."
