Description:

Nick Mucia -- Sifting through data: The search for a Z boson decaying into an electron and a muon

Abstract: I will present a search for Z->emu using data taken with the CMS detector in 2012. I will focus on analytical and experimental techniques which are used to focus on a specific subset of the vast quantity of collisions that take place at the LHC. I will show how these techniques are applied to a current search for a theoretical decay of the Z boson. 
 
Daniel Angles-Alcazar -- Simulating the evolution of galaxies and massive black holes across cosmic time

Abstract: In the currently accepted scenario for the formation of cosmic structure, primordial density fluctuations in the very early universe collapse by gravitational instability and grow hierarchically to give rise to the galaxy population that we see today.  From a theoretical point of view, understanding the connection between the initial conditions, observed as temperature fluctuations in the cosmic microwave background, and the formation of galaxies at different epochs requires incorporating a wide range of physical processes into one self-consistent model.  In this talk, I will describe recent efforts in this direction by means of cosmological hydrodynamic simulations including parametrized models of galactic winds and the growth of massive black holes at the centers of galaxies, both of which appear to be key ingredients in galaxy evolution.
