About the speaker: 

Yasmine Amhis is a French-Algerian physicist.  She studied at the University of Paris-Sud, Orsay, and obtained her PhD in physics while working on the LHCb experiment at CERN. After a postdoc at EPFL in Switzerland, she obtained a Chargée de recherche position at CNRS. In 2016, she received the Grand Prix Jacques-Herbrand for her work. She was the physics coordinator for the LHCb experiment at CERN from 2022 to 2024. She is currently a research director at IJCLab in Orsay. She is the author of “Tiny creatures at CERN”.

14:00 → 15:00 Matter and antimatter asymmetries at LHCb

The observed baryon asymmetry of the universe is one of the biggest unresolved questions in fundamental physics. Within the Standard Model of particle physics, matter-antimatter (CP) asymmetries in the quark sector are encoded by the imaginary parameter of the Cabibbo–Kobayashi–Maskawa matrix. Despite the tremendous experimental success of the CKM mechanism in describing quark mixing, its CP asymmetry is around ten orders of magnitude too small to explain the observed baryon asymmetry. The LHCb experiment at CERN’s Large Hadron Collider is one of the most sensitive instruments for seeking CP asymmetry sources beyond the Standard Model, with unparalleled reach for baryonic matter and hadrons containing charm quarks in particular. In this talk I will give an overview of LHCb’s latest CP asymmetry measurements and discuss the prospects of a second upgrade of the LHCb detector as an ultimate heavy flavour experiment specialised in searching for beyond Standard Model CP asymmetry sources.
