Beyond Standard Model

The Standard Model of particle physics is the set of quantum theories that governs the behavior of elementary particles and fundamental forces. It describes the strong, weak, and electromagnetic interactions. However, despite the huge successes of the Standard Model, there are many strong observational and theoretical reasons to believe that it is not the ultimate model to describe the nature....

Beyond Standard Model

DAMIC-M (Dark Matter in CCDs at Modane) is a near-future experiment that aims at searching for low-mass dark matter particles through their interactions with silicon atoms in the bulk of charge-coupled devices (CCDs). Pioneer in this technique was the DAMIC experiment at SNOLAB. Its successor, DAMIC-M, will have a detector mass 25 times larger and will employ a novel CCD technology (skipper...

15. Searches for effects Beyond the Standard Model in semileptonic decays of B mesons at LHCb

Beyond Standard Model

Search for Charge-Parity violation (CPV) in $B\to D^{\ast }\ell \nu$ transitions. In the Standard model (SM) there is no CP-asymmetry in this type of decays, however two New Physics (NP) possible ways to obtain CPV are investigated in this thesis. One possibility is given by the triple product asymmetries in four-body decays of B mesons, while the other possibility is the interference of two (or...

25. Higgs pair production in bb\gamma\gamma final state with ATLAS Run 2 at LHC

Beyond Standard Model

The Higgs boson self-coupling provides information about the structure of the Higgs potential.
A direct probe of the self-coupling of the Higgs boson is possible by studying Higgs boson pair production.
Furthermore, an enhancement of the Higgs boson pair production rate with respect to the Standard Model (SM) prediction would point to new beyond-the-Standard-Model (BSM) physics and may be...

23. Search for New Physics with unsupervised Machine Learning

Beyond Standard Model

The Stnadard Model of particle physics is the model that best describe our current knowledge of elementary particles and their interactions. However, it can't explain everything. For this reason, experiments like ATLAS tries to find the constituents of New Physics beyond the Standard Model.

In order to analyse the data produced by these experiments, Machine Learning is a very popular tool....
