173. Measurement of the anti-deuteron nuclear inelastic cross section with ALICE and implications for indirect Dark Matter searches

Quark matter and nuclear astrophysics

Oral Presentation

The measurement of low-energy cosmic anti-deuterons may reveal the existence of exotic processes such as dark-matter annihilation, since the production rate of these ions through ordinary secondary processes is very low. However, the lack of experimental data at low energies, where both the anti-deuteron production and inelastic cross sections are very poorly known, prevents precise...

56. Quarkyonic Matter and Neutron Stars

Quark matter and nuclear astrophysics

Oral Presentation

Masses and radii of neutron stars and the recent data from LIGO suggest that
the sound velocity is greater than or of the order of 1/3 at densities a few times that of nuclear matter. We show that this arises naturally if nuclear matter is Quarkyonic. Quarkyonic matter has a shell in the Fermi surface of nuclear matter
and Fermi sea of quarks. We discuss how this shell might arise dynamically

358. Continuity from neutron matter to color-superconducting quark matter with $^3 P_2$ superfluidity

Quark matter and nuclear astrophysics

Oral Presentation

Quark-hadron continuity has been well understood for three-flavor symmetric nuclear and quark matter, which is however a theoretically over-idealized environment. In this talk we clarify how quark-hadron continuity can be applied to neutron matter in the realistic neutron star environment. Our key observation is that neutron matter can be smoothly connected to the two-flavor...

294. Signatures of quark-hadron phase transitions in general-relativistic neutron-star mergers

Verônica Dexheimer (Kent State University)

Quark matter and nuclear astrophysics

Oral Presentation

Merging binaries of neutron stars are not only strong sources of gravitational waves, but also have the potential of revealing states of matter at densities and temperatures not accessible in laboratories. A crucial and longstanding question in this context is whether quarks are deconfined as a result of the dramatic increase in density and temperature following the merger. We present the...

543. Chirality transfer & chiral turbulence in gauge theories

Soeren Schlichting (Universität Bielefeld)

06/11/2019, 17:40

New theoretical developments

Oral Presentation

Sharing and transfer of chirality between gauge fields and fermion plays a crucial role for understanding the dynamics of anomalous transport phenomena such as the Chiral Megnetic Effect. We present a first principles study of the chirality transfer between gauge fields and fermions based on classical-statistical real-time lattice simulations. We demonstrate that a chirality imbalance in the...
