In this regard, the Higgs pair production is particularly sensitive to this coupling, while presenting a stimulating challenge due to the limited statistics available. In this talk, I present recent results from the ATLAS collaboration on measurements of HH production as predicted by the Standard Model and its possible enhancement through coupling modification or with the search for beyond-SM physics involving resonances producing HH pairs.

Mental Health of early career researchers is alarming. Several recent studies reported that PhD candidates are at a high risk of developing mental health disorders such as depression, anxiety, and burn-out. Importantly, Evens (2018) found that PhD students are 6 times more likely to develop mental health disorders in comparison with other highly educated individuals working outside of academia. Finally, Satinsky et al. 2021 showed that despite the growing evidence of mental health dangers for academics, little attention has been given to the ways to improve it and urged for more practical solutions.
In the light of these findings, the aim of this intervention is 1) to raise mental health awareness among academics 2) reduce the risks of developing mental disorders and finally 3) propose a practical solutions on how researchers can take care of their mental health, despite the challenging working environment. In particular, in this 1-hour seminar, studies on mental health and wellbeing in academia will be presented explaining the causes and prevalence of mental distress, followed by practical advice on how to detect and prevent mental health risks at the early stages and how to enhance wellbeing and life satisfaction on a daily basis.
Finally, in line with numerous studies indicating that “happy” employees are more motivated, present better resilience to stress, and are more efficient at work, we believe that improving the mental health of PhD researchers will benefit them individually, but also contribute to creating better working environment and potentially result in better work/research effectiveness for academic institutions.
I will briefly review some of the key properties of general relativity
that make its quantization so unlike the other fundamental forces. I
will explain how the approach known as loop quantum gravity faces this
challenge, and give a pedagogical introduction to the main ideas
behind it. The resulting scenario of a quantum and discrete spacetime
has already led to a broad phenomenology targeting observations from
primordial cosmology and black holes. I will then describe more recent
work, which explores the consequences that some of the loop quantum
gravity assumptions have in the structure of gravitational waves, and
which could potentially open new paths to phenomenology.
The multi-messenger astronomy aims to study astrophysical events through different messengers : GW, photons, neutrinos. The 170817 joint detection of GW and photons (at all wavelengths) has proven the relevance of multi-messengers studies. Yet it also showed the necessity of coordination and preparation of electromagnetic observations (from gamma to radio) to have relevant constraints on physical parameters. In this talk, I will present the Global Rapid Advanced Network Devoted to the Multi-messenger Addicts (GRANDMA), a network of telescopes aiming to detect, identify and characterize electromagnetic counterparts to gravitational-wave sources. I will detail the consortium, its capabilities, scientific program and public tools developed for the time domain astronomy. I will conclude by presenting a summary of our scientific results after O3 LIGO/Virgo run and the prospects we will be conducting to prepare the next GW observation runs (and possibly KM3NET campaigns).
