Search for the Chiral Magnetic Effect from RHIC Beam Energy Scan-II data with STAR

Room: hybrid event - zoom and 510 LSR Parity (left-right) symmetry violation in the weak interaction was discovered in 1956, winning the Nobel Prize in 1957. However, parity violation in strong interactions remains undiscovered. The strong interaction describes how quarks, fundamental constituents of matter, are bound together by gluons. Gluons, carrying color charges, can also interact with each other, causing an imbalance in the chirality (handedness) of quarks, known as chirogenesis. This phenomenon is analogous to baryogenesis (production of matter (baryons)) in the early universe, to which we owe our own existence. At the Relativistic Heavy-ion Collider (RHIC) at Brookhaven National Laboratory, a new state of matter is created known as Quark-Gluon-Plasma, where quarks and gluons are unbound. The collisions at RHIC also generate the most powerful magnetic fields on earth, providing an opportunity to study chirogenesis through the Chiral Magnetic Effect (CME). The Beam Energy Scan (BES) program at RHIC explores a variety of magnetic field conditions in terms of strength and decay time length. Scientists aim to detect CME-induced electric charge separation using the STAR detector, employing innovative methods to minimize background. We will present the findings of charge separation at BES-II in search for this local parity and charge-parity violation in strong interactions.
