[Theory-seminars] Seminars next week

[Carlota Andres Casas]

Dear all,


Here is a reminder for next week theory seminars:

Theory seminar:
Monday April 22nd, 1:00PM, Room L102

Jacquelyn Noronha-Hostler (Rutgers), "Influences of nuclear structure on the "little bangs" from ultrarelativistic heavy ion collisions"


Abstract:

Microseconds after the Big Bang, the universe was filled with an extremely hot and dense state of matter called the Quark Gluon Plasma. Then the tiniest building blocks of matter, quarks and gluons, were not yet confined inside of protons and neutrons but produced an exotic state of strongly interacting matter that behaved as a nearly perfect liquid. Over the past 15 years, collider experiments have been smashing heavy-ions together at nearly the speed of light in order to produce a tiny droplet with a radius (~ trillionth cm) and temperature high enough (~ a few trillion Kelvin) to recreate the Quark Gluon Plasma in the laboratory.  While the the evolution of the Quark Gluon Plasma liquid is well simulated via state-of-the-art relativistic viscous hydrodynamics, many questions still remain about the initial state immediately after the collision before hydrodynamics is even applicable. In recent years heavy-ion collisions have noted that the assumption of spherical nuclei in their ground state cannot account for experimental data, thus, initial conditions with deformed nuclear structure have been necessary to reproduce experimental data in ultra central collisions. In this talk we explore nuclei of interest such as 129^Xe and 238^U.


Theory seminar:
Wednesday April 24th, 1:00PM, Room L102

Martin Hoferichter (U. of Washington), "Effective field theories for dark matter direct detection"


Abstract:
In the interpretation of direct detection experiments scales ranging from the appearance of physics beyond the Standard Model down to nuclear energy levels matter, and for each energy region the appropriate degrees of freedoms need to be considered to extract robust constraints on the nature of dark matter. This task can be achieved by matching a tower of effective field theories that reveals how the dark matter properties are encoded in a handful of couplings accessible in experiment. In the talk I will give an overview over this approach, concentrating on the nuclear and hadronic physics required to turn limits on the direct detection rates into constraints on the dark matter parameter space.
