Their study allows us to probe some of the most extreme phenomen a in our Universe and to investigate its fundamental physics properties. T he Pierre Auger Observatory\, with its upgrade\, AugerPrime\, and the futu re Southern Wide-field Gamma-ray Observatory\, are two of the most ambitio us astroparticle physics facilities in the world. In this talk\, I will br iefly discuss the technological challenges and physics opportunities conne cted with the study of these physics objects\, which defy our understandin g about acceleration mechanisms and particle interactions.Speaker: Catarin a CosmeTitle: Glimpses of a physicist journey to the dark side of the Univ erseAbstract: In this talk\, I will introduce myself\, give an overview of my academic path\, and briefly discuss the main lines of investigation th at I have pursued so far.

I discuss briefly the current and future status of the extr action of the CKM matrix elements in the Standard Model (SM). I also comme nt on the role charm physics can play in testing the Kobayashi-Maskawa mec hanism\, responsible for generating CP violation in the quark sector of th e SM.

Are there symmetries un derlying the flavour structure of the SM? Why are neutrino masses so small ? In this talk I will briefly describe two neutrino experiments which will help elucidate these puzzles: DUNE\, which is set to discover or rule out matter-antimatter asymmetry in neutrino oscillations\; and SND@LHC\, whic h will measure for the first time interactions of neutrinos of all three f lavours produced at CERN'\;s Large Hadron Collider.

Title: Exploring the ex treme energy Universe

Abstract: Ultra- high-energy cosmic rays (UHECRs) and very high-energy gamma rays are the h ighest-energy known particles and radiation\, respectively. Their study al lows us to probe some of the most extreme phenomena in our Universe and to investigate its fundamental physics properties. The Pierre Auger Observat ory\, with its upgrade\, AugerPrime\, and the future Southern Wide-field G amma-ray Observatory\, are two of the most ambitious astroparticle physics facilities in the world. In this talk\, I will briefly discuss the techno logical challenges and physics opportunities connected with the study of t hese physics objects\, which defy our understanding about acceleration mec hanisms and particle interactions.

Abstract: Flavo r physics plays a central role in particle physics: for instance\, it led to the discovery of Charge-Parity (CP) violation. I discuss briefly the cu rrent and future status of the extraction of the CKM matrix elements in th e Standard Model (SM). I also comment on the role charm physics can play i n testing the Kobayashi-Maskawa mechanism\, responsible for generating CP violation in the quark sector of the SM. Finally\, I discuss bounds on dif ferent categories of generic New Physics contributions.

Title: Neutrino experiments at the i ntensity and energy frontiers

Abstract: Neutrinos are some of the least well understood particles in the Standar d Model (SM) and play a central role in major open questions in Physics: H ow did matter come to dominate over antimatter in the history of the Unive rse? Are there symmetries underlying the flavour structure of the SM? Why are neutrino masses so small? In this talk I will briefly describe two neu trino experiments which will help elucidate these puzzles: DUNE\, which is set to discover or rule out matter-antimatter asymmetry in neutrino oscil lations\; and SND@LHC\, which will measure for the first time interactions of neutrinos of all three flavours produced at CERN'\;s Large Hadron Collider.
