Simple generalizations of well known BSM scenarios can lead to dramatic signals at colliders, providing interesting theoretical playgrounds and motivating new methods to isolate non-standard experimental signals. In this talk I will consider warped extra-dimensional models with multiple branes in the IR and discuss various possibilities and related collider signals. One generic feature of this...

We discuss a ∼ 3 σ signal (local) in the light Higgs-boson search in the diphoton decay mode at ∼ 96 GeV as reported by CMS, together with a ∼ 2 σ excess (local) in the b ̄b final state at LEP in the same mass range. We interpret this possible signal as a Higgs boson in the 2 Higgs Doublet Model with an additional real Higgs singlet (N2HDM). We find that the lightest Higgs boson of the N2HDM...

I present the most general bounds one can make on the phenomenology of hidden sectors with conformal symmetry, which are weakly coupled to the SM. Without the need to specify their particle or symmetry content, we have derived a consistent description of final states in a generic CFT, and have applied it to current experimental runs. Our analysis covers a wide range of phenomena: we...

Observations at astronomical and cosmological levels suggest the existence of a new form of non-luminous matter that interacts gravitationally with baryonic matter. The XENON1T detector, located at the underground National Laboratory of Gran Sasso in Italy, was designed and built to detect nuclear recoils from particles that may constitute the nature of this Dark Matter, their existence...

The EDELWEISS collaboration is performing direct searches for light Dark Matter particles using cryogenic germanium detectors equipped with a charge and thermal signal readout. This versatile and highly performing technology opens new possibilities for searches for signals involving either electrons or nuclear recoils. This is attested to by results on Axion-Like Particles in the keV range,...

The COSINE experiment aims at direct detection of Weakly Interacting Massive Particle (WIMP) using NaI(Tl) detectors, the same target material as the DAMA/LIBRA which claims to observe an annually modulated WIMP signal. The first phase of the experiment with ~106 kg of NaI(Tl) crystals consists of several shield structures including a liquid scintillator veto counter and installed at the...

ANAIS (annual modulation with NaI Scintillators) is a dark matter direct detection experiment located at the Canfranc Underground Laboratory (LSC, Spain). Its main goal is to proof or refute in a model independent way the DAMA/LIBRA positive result: an annual modulation in the low-energy detection rate compatible with the expected signal induced by WIMPs in the galactic halo. This signal,...

The evidence for the existence of Dark Matter is well supported by many cosmological observations. Separately, long standing problems within the Standard Model point to new weakly interacting particles to help explain away unnatural fine-tunings. The axion was originally proposed to explain the Strong-CP problem, but was subsequently shown to be a strong candidate for explaining the Dark...

The NEWSdm experiment, based on nuclear emulsions, is proposed to measure the direction of WIMP-induced nuclear recoils. We discuss the potentiality, both in terms of exclusion limits and potential discovery, of a directional experiment based on the use of a solid target made by newly developed nuclear emulsions and read-out systems reaching sub-micrometric resolution. We also report results...

The DARWIN experiment is a proposed next-generation dual-phase time projection chamber which will operate 50 tonnes of natural xenon and whose primary goal will be to explore the entire experimentally accessible parameter space for WIMPs. Besides its unprecedented sensitivity to WIMPS above a mass of 5 GeV/c2, such a large detector, with its low-energy threshold and ultra low background level,...

The Weakly Interacting Massive Particle or `WIMP' has been a widely studied solution to the dark matter problem. A plausible scenario is that DM is not made up of a single WIMP species, but that it has a multi-component nature. In this talk I give an overview of recently published work in which we studied direct detection signals in the presence of multi-component WIMP-like DM. I will give an...
