The **complementarity of direct, indirect and collider** searches for dark matter has improved our understanding concerning the properties of the dark matter particle. We will **review the basic concepts** that these methods rely upon and highlight what are the most important information they provide when it comes down to interpret the results in terms of Weakly Interacting Massive Particles...

Proton decay is a defining prediction of Grand Unified Theories (GUTs).
It provides a unique test of energies around $10^{(14-16)}$ GeV,
which are unreachable by accelerators and which could also be
connected with other physics such as neutrino masses.
We will present results of recent nucleon decay
searches at the Super-Kamiokande experiment.
Analyses of typically dominant non-SUSY and...

Gravitational effects observed at different astronomical scales indicate that ~85% of the matter content of the Universe consists of dark matter (DM), whose particles properties remain unknown. Weakly-interacting massive particles (WIMPs) are a well-motivated class of DM candidates, that in some models have typical masses between 1 and 10 GeV.
The purpose of the Super Cryogenic Dark Matter...

In recent years growing interest in low mass dark matter particles can be noted. Cryogenic experiments like CRESST are well suited to search for low mass WIMPs with masses in the GeV and sub GeV region. CRESST is based on the phonon/light technique and uses scintillating CaWO$_4$ crystals as target material. CRESST-II, which stopped data taking in July 2015, allowed an accurate measurement of...

Weakly interacting massive particles (WIMPs) are a very popular explanation for the nature of dark matter. The XENON100 experiment and its next generation the XENON1T experiment aim for detecting WIMP-nucleon interactions using a dual phase time projection chamber (TPC) with a total liquid xenon target of 161 kg and 3500 kg, respectively.
This talk will present the most recent results of...

Precision measurements in particle physics are often used to infer information about New Physics at some ultraviolate scale. In my talk, I explore the alternative route: new weakly-coupled physics in the IR, inducing deviations for the precision experiments. I give a classification to the precision measurements (EDMs, lepton flavour violation, g-2, quark flavour etc) as to whether they provide...

The direct detection of dark matter – accounting for 85% of the mass content of the Universe – is one of the most important scientific missions of the 21st century and any discovery will provide an incontrovertible signature of physics beyond Standard Model. Weakly interacting massive particles (WIMPs) that arise naturally in several models are compelling candidates.
The LUX experiment is...

Searches for direct interactions of dark matter with standard-model particles at colliders are challenging and often constrained by direct detection experiments. However, many scenarios predict mediator particles with electroweak interactions, which could well be in reach of collider experiments. Focusing on Higgs-portal models with fermion dark matter, I will present the search strategies and...

Recently, a new mechanism to generate a naturally small electroweak scale has been proposed, the so-called "relaxion" . It exploits the coupling of the Higgs to an axion-like field and a long era in the early universe where the axion unchains a dynamical screening of the Higgs mass. We present a new realization of this idea with the new feature that it leaves no signs of new physics up to a...

Since the breakthrough discovery that neutrinos are massive (2015 Nobel Prize in Physics and 2016 Breakthrough Prize in Fundamental Physics), pinpointing their total mass has become one of the greatest challenges in science today, at the cross-road between particle physics, astrophysics, and cosmology. After an introduction on the impact of massive neutrinos in structure formation, with a...

On September 14, 2015 at 09:50:45 UTC the two LIGO detectors simultaneously observed a transient gravitational-wave signal. The signal matches the waveform predicted by general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. It was observed with a matched-filter signal-to-noise ratio of 24 and a false alarm rate estimated to...
