Dear all,

We are delighted to invite you to the next edition of our COMETA Colloquium series.

The seminar takes place on the 24th of March at 4 PM CET. The seminar is virtual and open to everyone. The Zoom room can be accessed via indico: https://indico.cern.ch/event/1508915/

This lecture is given by Federica Fabbri (ATLAS).

Measurement of quantum information inspired observables at LHC

Abstract: A few years ago, the study of quantum information principles in high-energy collisions was reignited by a proposal to measure entanglement between top-quark pairs at the LHC. Initially focused on entanglement in these systems, this research has since expanded significantly, revealing a much broader landscape. Today, new studies emerge almost daily, extending these investigations to diverse final states, exploring the fundamental limitations of such measurements, and integrating novel concepts from quantum information science and computing into high-energy physics. Additionally, these principles are now being leveraged to search for physics beyond the Standard Model, with promising early results from the CMS collaboration. In this colloquium, I will provide an overview of how these measurements are performed, highlighting the first experimental results in top-quark pair final states. I will then discuss how these concepts can be extended to both resonant and non-resonant diboson final states.

Please, distribute this announcement at your home institute or to collaborators worldwide!

Additionally, we would like to invite you to participate in our satisfaction survey about the COMETA colloquium which will be open until the 27th of April: https://forms.gle/FDLwPRHbNcvJcvuC9 . Have your say and let us know what you like or where you see improvements necessary! It only takes 5 mins of your time.

With best regards,
