Gravitational waves from the Big Bang

Mark Hindmarsh
University of Sussex, UK

Abstract: The recent detection of gravitational waves by LIGO confirms a 100-year-old prediction of the general theory of relativity.  I outline the significance of the discovery, and explain how the future space-based gravitational wave experiment LISA will probe the first few picoseconds of the Big Bang, when the Higgs field “turned on".

Higgs boson: What do we not know?

Ricardo Gonçalo
LIP

Abstract: The Higgs boson was the last missing particle predicted by the Standard Model of particle physics. After the widely publicized discovery of the Higgs boson in 2012, what have Higgs hunters been doing? And why? I will review the theory of the Higgs sector and what we have learned experimentally since the discovery. Finally, I will take a look at what else we are trying to find out.
