Beyond the Standard Model Higgs bosons and dark sectors at the LHC

Abstract: I will discuss the motivations and phenomenology of a set of models containing beyond the Standard Model Higgs bosons with a mass either above or below 125 GeV. I will show how Higgs bosons can be used to unravel the presence of dark particles, i.e. particles not charged under the gauge symmetries of the SM. I will particularly highlight the discovery prospects for these new degrees of freedom at the LHC Run III and at the HL-LHC.

Gravitational Wave Astronomy

Abstract: Direct gravitational wave observations from coalescing binary black holes and binary neutron stars have opened a new window to observe the universe, to learn about some of the most extreme objects within it, and to further our understanding of the fundamental theory of gravity. Particular notable were the first observation of a binary black hole merger on Sep 14, 2015, as well as the multi-messenger observation of two coalescing neutron stars on Aug 17, 2017. These lectures will give a brief overview of this subject area. After an introduction about gravitational waves, black holes & neutron stars, we will briefly describe the interferometric gravitational wave detectors and analysis methods at the heart of the current observations. We will do an in-depth tour of the results obtained since the first GW discovery on Sep 14, 2015. The lectures will close with an outlook on future plans and prospects, both in the currently active high-frequency band, as well as the low-frequency and ultra-low-frequency bands.

Experimental searches for axions and axion-like particles

Abstract: Axions and other very light axion-like particles (ALPs) appear in many extensions of the Standard Model, and are leading candidates to compose part or all of the missing matter of the Universe. They also appear in models of inflation, dark radiation, or even dark energy, and could solve some long-standing astrophysical anomalies. The physics case of these particles has been considerably developed in recent years, and there are now useful guidelines and powerful motivations to attempt experimental detection. Admittedly, the lack of positive signal of new physics at the high energy frontier, and in underground detectors searching for weakly interacting massive particles, is also contributing to the increase of the interest in axion searches. The experimental landscape is rapidly evolving, with many novel detection concepts and new experiments being proposed lately. I will review the different experimental strategies being followed to search for ALPs potentially composing our dark matter galactic halo, as well as ALPs emitted by the Sun or produced at laboratories. I will focus on the new experimental approaches and their complementarity, but will also review the most relevant recent results from the consolidated strategies and the prospects of new generation experiments under consideration in the field. I will discuss the prospects to probe a large fraction of relevant parameter space in the coming decade.
