    Physics Colloquium

    "eRHIC Machine Design"

    Presented by Thomas Roser, BNL

    3:30 pm, Large Seminar Room, Bldg. 510

    Tuesday, May 3, 2016, 3:30 pm

    Hosted by: 'Robert Pisarski'

    With the addition of a 20 GeV polarized electron accelerator to the existing Brookhaven Relativistic Heavy Ion Collider (RHIC), the world?s only high energy heavy ion and polarized proton collider, a future eRHIC facility will be able to produce polarized electron-nucleon collisions at center-of-mass energies of up to 145 GeV and cover the whole science case as outlined in the Electron-Ion Collider White Paper and endorsed by the 2015 Nuclear Physics Long Range Plan with high luminosity. The presentation will describe the eRHIC design concepts and recent efforts to reduce the technical risks of the project.

    "Fluid dynamics for the anisotropically expanding quark-gluon plasma"

    Presented by Dennis Bazow, The Ohio State University

    Friday, May 6, 2016, 2:00 pm

    Hosted by: ''Soeren Schlichting''

    Local momentum anisotropies become large in the early stages of the quark-gluon plasma created in relativistic heavy-ion collisions, due to the extreme difference in the longitudinal and transverse expansion rates. In such situations, fluid dynamics derived from an expansion around an isotropic local equilibrium state is bound to break down. Instead, we subsume the slowest nonhydrodynamic degree of freedom (associated with the deviation from momentum isotropy) at leading order defining a local anisoptropic quasi-equilibrium state, thereby treating the longitudinal/transverse pressure anisotropy nonperturbatively. Perturbative transport equations are then derived to deal with the remaining residual momentum anisotropies creating a complete transient effective theory called viscous anisotropic hydrodynamics. This approach has been shown to dramatically outperform viscous hydrodynamics in several simplified situations for which exact solutions exits but which share with realistic expansion scenarios the problem of large dissipative currents. We will discuss the present status of applying viscous anisotropic hydrodynamics to the phenomenological description of the quark-gluon plasma in realistic expansion scenarios.

    "Evolution of the jet opening angle distribution in holographic plasma"

    Presented by Andrei Sadofyev, MIT

    2 pm, Small Seminar Room, Bldg. 510

    Friday, May 13, 2016, 2:00 pm

    Hosted by: 'Soeren Schlichting'

    Energetic jets are particularly interesting probes of QGP created in heavy ion collisions. Recently a lot of progress was made in attempting to describe the jet evolution in holography. In this talk I'll present an application of a simple dual model to study the jet substructure starting with energy and angle distributions from pQCD. In particular I will show that there are two competing effects: (1) each individual jet widens as it propagates through plasma; (2) the final jet opening angle distribution becomes narrower since wider jets lose more energy and less likely to survive. So, the mean opening angle for jets with a given energy can easily shift toward smaller angles, even while every jet in the ensemble broadens.

    Physics Colloquium

    "Sterile Neutrinos as the Origin of Dark and Baryonic Matter"

    Presented by Mikhail Shaposhnikov, EPFL

    Tuesday, June 21, 2016, 3:30 pm

    Hosted by: 'Robert Pisarski'

    I will discuss how three sterile neutrinos alone can simultaneously explain neutrino oscillations, the observed dark matter, and the baryon asymmetry of the Universe without new physics above the Fermi scale. The experimental prospects to search for these particles will be outlined.
