New opportunities to probe nuclear deformation using high-energy heavy-ion collisions

by Prof. Jiangyong Jia (Stony Brook University and Brookhaven National Laboratory)

Monday, September 27, 2021 from to (Asia/Shanghai)
at CHEP ( B105 )
Description
High-energy heavy-ion collisions, a branch of nuclear physics that focus on study of quark-gluon plama (QGP) and nuclear phase diagram, have always assumed an initial condition from the nuclear structure physics, e.g. the Woods-Saxon geometry. Recent progress in hydrodynamic modeling together with the wealth of precision collective flow data, however, allow us to not only perform quantitative extractions of the transport properties of the QGP, but very importantly start to strongly constrain the initial state of the colliding nuclei. In this talk, I will discuss the exciting possibility of imaging the shape of atomic nuclei using precision flow measurements, including the quadruple, triaxial and octupole deformations. I will discuss how the shape information probed by heavy ion collision might be different or complementary to those obtained in the nuclear structure experiments. I will argue how a carefully planned system scan of stable species in the nuclear chart at high-energy collider facilities could open new direction of research in nuclear physics.
