Charla de Farida Fassi «Searches for New Physics at the LHC using challenging signatures with the ATLAS detector»

Lecturer:  Farida Fassi, Mohammed V University in Rabat, Faculty of Sciences. Morocco

Abstract: The Large Hadron Collider (LHC) at CERN, the largest and most complex machine ever built will extend the frontiers of particle physics with its unprecedented high energy and luminosity. The ATLAS experiment is the largest particle detector at LHC, targets to detect the tiny subatomic particles and study the fundamental constituents of matter to better understand the rules behind their interactions. The ATLAS experiment at the LHC has a broad search program covering a wide variety of models of physics beyond the Standard Model (BSM). Various BSM theories predict unique signatures that are difficult to reconstruct and for which estimating the background rate is also a challenge. With the large amount of data gathered by the Run-2 of the LHC, the production of four top quarks (𝒕𝒕 𝒕𝒕 ) has become a very interesting probe of the Standard Model (SM) and beyond. In the SM of particle physics, 𝒕𝒕 𝒕𝒕 production is an extremely rare process with a cross section of approximately 12 fb. In extensions of the SM with top-philic new states, the four-top production rate can be enhanced considerably. Highlights from recent new physics searches with the ATLAS detector at the CERN LHC will be presented. They include searches for the SM 𝒕𝒕 𝒕𝒕 and BSM 𝒕𝒕 𝒕𝒕 , among others. Results are based on analysis of proton-proton collision data recorded at a centre-of-mass energy of 13 TeV.

Charla Antoine Kouchner «High Energy Neutrino Astronomy from the Deep Sea»

Antoine Kouchner ,  Laboratoire Astroparticule et Cosmologie (APC) Paris, is the ANTARES experiment spokesperson

Abstract: Messengers of the infinitely small, neutrinos provide us with valuable insights into the fundamental laws of physics. Messengers of the infinitely large, traveling on cosmological distances, they are privileged probes of cataclysmic astrophysical phenomena.

Neutrino Telescopes, buried deep in the sea/lake/ice are trying to meet this double challenge. These detectors consist of a 3D matrix of photomultipliers that detect the Cherenkov light inferred by the displacement of charged particles produced when neutrinos interact inside or around the detector.

After a brief historical introduction, I will review the latest results from the first generation deep-sea neutrino telescope ANTARES and the expectations and status of the next generation detector KM3NeT, both immersed in the Mediterranean Sea. In this context, synergies with Earth and Sea sciences will be mentioned.

Some emphasis will be placed on the potential of neutrino telescopes for the determination of the neutrino mass ordering through oscillation studies of atmospheric neutrinos in the GeV range (KM3NeT/ORCA) in the Mediterranean Sea.

Charla de Andrés del Pino Molina «Gaia’s revolution: An open window to our Galaxy and its surroundings»


Lecturer: Andrés del Pino Molina. Centro de Estudios de Física del Cosmos de Aragón (CEFCA). Astrophysics researcher with a strong computational and statistic background. Interested in resolved stellar populations, galaxies dynamics, and star formation

Abstract: The Milky Way system (MW) harbors dozens of known dwarf galaxies. Some of these systems have been studied for decades, offering us a glimpse on how diverse dwarfs can be in terms of their star formation histories, chemical composition, masses, etc. This has raised questions about the origin of these systems and on the possible mechanisms involved in their evolution. From the dynamical standpoint, some of the most obvious mechanisms proposed invoke the interaction of dwarfs with their massive host galaxy. However, based mostly on N-Body predictions and just line-of-sight velocity measurements, the discussion about the strength and efficiency of these mechanisms have remained largely speculative. Thanks to its unprecedented astrometric precision, the Gaia mission has changed that, giving us access to accurate 3D systemic motions of many known dwarfs satellites of the MW. For the first time, we can study the orbital histories of the MW satellites, which can shed light on the nature versus nurture discussion for these systems. In this talk, I will present a general overview on how the internal properties of  dwarfs are linked to their orbital history and on how the interaction with the MW has shaped them into the system we observe today.

Charla de G. Raffelt: «Stars as Particle-Physics Laboratories: Old Ideas and New Developments»

Georg G. Raffelt, Max-Planck-Institut für Physik. His research is in the areas of theoretical astroparticle physics and cosmology. In particular, it revolves around weakly interacting particles (neutrinos, the hypothetical axion, or weakly interacting dark matter candidates), their role in astrophysics and cosmology.
