In the Standard Model, hadron resonances emerges from the interaction between quarks and gluon. The nucleon matter is composed of baryons, three quarks states, interacting via the exchange of mesons, quark-antiquark pairs.

Quantum chromodynamics predicts the existence of other types of quark configurations. They are generically called ``exotic hadrons''.

Over the last few years there have been various measurements where the Standard Model fails to agree with experiment.
I will attempt to give a summary of the different places where the disagreements occur, why we do (or why not) these are believable signs of physics beyond the Standard Model, and what the current results can tell us about how to go beyond the Standard Model.

Our recently acquired ability to detect gravitational waves has expanded our senses and our possibilities of inquiring the Universe. As a new era of gravitational wave detections rapidly unfolds, the importance of having accurate models for their signals becomes increasingly important. In this context, we will discuss numerical simulations of black hole binaries. In particular, we will focus...

M dwarfs are the smallest and coolest stars on the main sequence. They are the most common stars in the Galaxy and are known to show the highest rocky planets occurrence. As a result, they may host most of the Universe’s Earth-sized planets orbiting in the Habitable Zones of main sequence stars. Among several parameters to determine if an exoplanet could possibly host life, one of them is the...

The Higgs boson, responsible for the mass of the SM fundamental particles, plays a central role in propounding New Physics (NP) that might shed some light on the still unanswered questions present within the standard frame of particle physics. For example, the appearance of resonances in the scattering of longitudinally polarized vector bosons (intimately related to the Higgs mechanism) would...

The phenomenon of neutrino oscillations is the first confirmed experimental evidence that the Standard Model needs to be extended. Thus, they are an excellent door to address new physics beyond the Standard Model.
However, what do we mean when we say that a neutrino oscillates? What kind of new physics could there be? What experimental evidence is there of such new physics? In this brief...

We study the exotic doubly charmed $D^* D$ system providing a natural explanation for the $T_{cc}^+$ recently seen by LHCb, in terms of $D^{*+}D^0$ and $D^{*0} D^+$ with isospin $I=0$. The width is evaluated accurately based on the decay widths of the $D^*$ states. The $D^0 D^0 \pi^+$ decay mode of the bound state formed is studied in detail, showing a narrow peak below the $D^{*+}D^0$...

The existence of Dark Matter (DM) is one of the most important indications of physics beyond the Standard Model of particle physics. One promising approach is to consider DM as Weakly Interacting Massive Particles. These candidates have evoked a prominent interest; many experiments explore Weakly Interacting Massive Particles, one of the approaches to detect them is Direct Detection which is...

The LIGO and Virgo interferometers have detected gravitational waves (GW) from several dozens of coalescing binary black holes (BBHs). Several formation channels are able to explain the BBH merger rate, leaving their origin an open question. The dynamical formation of BBHs in dense stellar systems is a promising model and it predicts that a fraction of BBHs have measurable orbital...

QCD Axions can be produced in various ways in the Early Universe by scatterings and decays from Standard Model particles, forming thus a Cosmic Axion Background that contributes to the abundance of relativistic relics (N_eff). We review in various setups how this is already constrained by present experiments and how it could be observed by future CMB experiments, in particular focusing on the...

The LIGO and Virgo gravitational wave detectors have opened a new window to the universe. We already have over 50 gravitational wave detections. I will briefly mention what we have learned from these events, and how we are preparing for an era when gravitational wave detections are expected on a daily basis. In particular, I will discuss gravitational wave lensing, when another object...

Gamma-ray binaries are extreme accelerators that display gamma-ray emission up to multi-TeV energies. These systems are composed of a massive OB-type star and a compact object that show a non-thermal spectral energy distribution that peaks in the MeV-GeV band and is modulated with the orbital period. Currently, only 9 of such extreme accelerators are known. However, some properties of these...

Neutrinoless double-beta ($0\nu\beta\beta$) decay is a hypothetical nuclear process in which two neutrons turn into protons (or vice versa) but, unlike in the standard double-beta decay, no neutrinos are emitted. Several large-scale experiments worldwide are dedicated to observing it. When observed, the lepton-number-violating process would provide unique vistas beyond the Standard model of...

Primordial black holes (PBHs) are one of the current most interesting candidates to be the dark matter. Not only they fulfill the basic criteria needed for dark matter, they do so without the need to invoke a new set of existing particles. While this might make them look ideal, their formation is not so simple and often requires some form of new physics too. Furthermore a large number of...

The Large Magellanic Cloud is a satellite galaxy of the Milky Way at a distance of about 50 kpc visible from the southern hemisphere. Together with its companion, the Small Magellanic cloud, form a perfect laboratory to test methodologies and models designed for external galaxies. Their proximity to the Milky Way makes them suitable to study their morphology and interaction using Gaia (ESA)...

The concept of lepton universality, where the muon and tau particles are simply heavier copies of the electron, is a key prediction in the Standard Model (SM). In models beyond the SM, lepton universality can be naturally violated with new physics particles that couple preferentially to the second and third generation leptons. Over the last few years, several hints of lepton universality...

The Gaia satellite (ESA) is revolutionising our view of the Milky Way providing information for over 1500 million sources. However, further data is requested to complete the picture, in the shape of photometric and spectroscopic surveys. I will review the main characteristics of the IGAPS photometric and the WEAVE spectroscopic survey, describe the main results we have obtained so far using...

Neutron stars are fascinating astrophysical objects, which provide insight into some of the most extreme properties of matter. In this talk, I will discuss two different theoretical instances of exotic physics in the interior of neutron stars: superfluidity and dark matter interactions. I will discuss how observations on neutron stars can provide insight into some of these formal developments,...

In the last few years, the field of star formation has experienced significant advances thanks to the major improvement in instrumentation. The increase in angular resolution and sensitivity make now possible to study with unprecedented detail the obscured regions in the Milky Way, the protostellar embryos, unveiling the physical processes that give rise to the formation of Sun-like stars as...

Space research has usually been based on big missions. Their development times (~decades) and associated budgets (~100M€) require a strong commitment, implying that only a small number of research missions are finally implemented.
