Baryogenesis and New Physics
February 4, 2015 | BSLC 001 | 3:00 PM
Carlos Wagner, University of Chicago/Argonne

Although physical reality seems to be well described by the Standard Models of Particle Physics and Cosmology, there are many open questions that do not have a direct answer within this framework. An important one is why is there Matter and not Antimatter in the Universe. The conditions for a dynamical generation of the asymmetry between matter and antimatter (baryogenesis) are well known, but cannot be fulfilled within the Standard Models framework. I will explain what are the basic conditions that must be fulfilled for baryogenesis to occur, some general classes of models in which baryogenesis is realized and the possible tests of these models in the near future.

Sterile Neutrinos in Particle Physics and Cosmology

Scott Dodelson, University of Chicago

The matter particle with the smallest mass, the neutrino, is also the most abundant in the Universe. Since their discovery, neutrinos have continually surprised us. Every time we think we understand the full scope of neutrino physics, data prove us wrong. We now understand the full scope of neutrino physics and can explain almost all observations with a simple 3-flavor model. Will upcoming data from accelerators and the cosmos prove us wrong yet again?

Overview of the 2015 Planck full mission results
March 4, 2015 | BSLC 001 | 3:00 PM
Jean-Loup L Puget, Institut d'Astrophysique Spatiale, univeresité Paris Sud

The Planck collaboration has released the results from the full mission including polarisation. The Planck space mission has fulilled its initial goal of extracting essentially all the cosmological information in the temperature map of the Cosmic Microwave Background. It has also detected the polarisation cosmological signals with unprecedented sensitivity over the whole sky.
The Planck mission performances will be illustrated by some spectacular improvements in calibration and reduction of polarized sytematic effects. The Planck view of the polarized microwave sky will be presented. The extreme stability of the L-CDM cosmological parameters determined either from the temperature or polarization data is leading to a « standard cosmolgy model ». This includes also parameters related to the primordial universe physics. The polarised foreground emission from interstellar dust has been mapped with a spectacular accuracy. The claim for detection of primordial gravity waves from the BICEP2 team using CMB data aquired from south pole will be discussed in the light of the dust B modes signal observed by Planck and the recent BICEP2-Plkanck paper. The future of the search for primordial B modes will be discussed.
