Particle Physics Seminar: Factorization and Universality in Nuclear Physics

Zoom: https://tau-ac-il.zoom.us/j/82648164044

Abstract:

The study of dilute, strongly interacting quantum gases reveals universal properties that transcend the specifics of individual systems.

These features arise from their short-range behavior and are encapsulated in a key quantity called the “contact”, which quantifies the probability of two particles being in close proximity.

In this talk, I will introduce the contact theory and its extension to nuclear and molecular systems beyond the zero-range limit. I will demonstrate its applicability in analyzing nuclear electron scattering and photoabsorption reactions. Additionally, I will discuss how mean-field approximations, such as the nuclear shell model, can effectively estimate the contact, offering valuable insights into the underlying physics.
