The manager of the Institute is going to explain the different services the secretariat provides for the researchers.
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...
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...
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...
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 Technological Unit of the ICCUB is actually providing several currently groups of ICCUB with services, such as instrumentation and software development, in order to support their contributions to international collaborations. Many developments on instrumentation are related to sensitive photosensor readout technology with key contributions in international projects as LHCb, CTA, HERD and...
The ICCUB Technological Unit is contributing to the software development and data processing of several projects. The most important one is Gaia, both on its data processing and on its catalogue validation and data mining aspects, as well as Virgo, where our contributions are ramping up. Besides these, we also participate on several other projects, and we expect to get more manpower soon to...
