QCD axions as dark matter and their potential detection by gravitational microlensing

Jordi Miralda Escudé es ICREA Professor of Astrophysics Institut de Ciències del Cosmos

Abstract:The most distant single stars we have observed are in cases of extreme gravitational lensing magnification, when the source star crosses a lensing caustic of a cluster of galaxies that is affected by microlensing. This has enabled detections of stars at redshifts above unity with HST, and now with JWST to even fainter levels. If dark matter is smoothly distributed, microlensing should be caused only by intracluster stars, with rates and lightcurves of caustic crossings that have precise statistical predictions. Deviations from the shapes and other characteristics of these lightcurves are then a powerful probe to small-scale granularity in the dark matter, which is unavailable through other astronomical observations. In particular, if the QCD axion is present in the dark matter, minihalos predicted to have formed around the epoch of equalization can affect the lightcurves of stars that are supermagnified when crossing microlensing caustics.

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

gloriapor gloria

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.

«Global Scientific Cooperation builds bridges between Nations» by Farida Fassi

gloriapor gloria

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

Abstract: The last few decades have witnessed the creation of Big Data that has revolutionised the knowledge outcomes within and beyond multi-disciplinary science, enabling novel highly efficient ways to plan, conduct, disseminate and assess research. Global research projects demonstrate what humankind is able to achieve the most challenging goals when collaborating together coherently towards a common target. Science and the scientific knowledge transfer dissemination facilitate the dialogue among cultures and are the key instrument in fostering peaceful relations between nations. The Muslim world has the ability to use science for the benefit of its people. Therefore, it is vital for the contemporary Muslim world to strengthen its commitment to the modern and global scientific projects, contributing to long-term sustainable training through committed investments in research and development. International associations are a great common denominator in the culture of scientific activities. Particle physics field looks at the most fundamental structure of the universe – the particles that are its most basic building blocks, and the ways they interact with each other. The field has always been an early adopter of new technologies, applying them in the state-of-the-art discovery machines and experiments that produce floods of Big Data that can be analysed anytime and anywhere using shared and interlinked of heterogeneous research data via large digital research infrastructures. The talk will address the role of such global research projects in science, including Big Science era, to carrying the light of learning through global collaboration, in particular at CERN, producing the best scientists and innovators the world has ever seen. What can be achieved from such global science endeavours? The talk will describe the fascinating mixture of science bridging cultures and nations.

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

gloriapor gloria

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.
