Primordial neutrinos from the Big Bang are about 100 times more prevalent than solar neutrinos, and at least two-thirds of them are now non-relativistic.  These relic neutrinos, which have never been detected, decoupled in the early universe predominantly in helicity eigenstates.   As this talk will discuss, their subsequent propagation through gravitational inhomogeneities and even background gravitational radiation, as well as cosmic and galactic magnetic fields partially flips their helicities, and can produce noticeable effects in their eventual detection.

A main goal of the experimental program at the Large Hadron Collider is the study of the quark-gluon plasma (QGP), a new phase of nuclear matter that exists at high temperature or density, and in which the quarks and gluons are deconfined.

Tyler's talk will show how by combining robust theoretical and observational input we can see evidence for the transition between hadronic and quark matter along the stable neutron-star sequence, indicating that neutron stars indeed probe the transition region of dense QCD

The Lagrangian that defines quantum chromodynamics (QCD), the strong interaction piece of the Standard Model, appears very simple.

One of the greatest challenges in contemporary physics is presented by the emergence of a nuclear-size mass-scale in Nature

In this talk, the motivation for and recent outcomes of the experimental hunt for the macroscopic footprints of quantum spin in the relativistic heavy-ion collisions will be presented and the theoretical challenges connected with formulating its collective description will be discussed.

The talk is based on  arXiv:2110.13521

The study of the properties of neutron stars is presently entering a golden age.

This talk will report on recent breakthroughs in understanding the extreme environment in which the formation of the heavy elements occurs, as well as open questions regarding the astrophysics and nuclear physics involved.

Recent analyses on the diffractive electroproduction of ρ mesons have corroborated the underlying assumption that the small-size dipole scattering mechanism is at work, thus validating the use of the HEF formalism.
