14. A neural likelihood estimator for fast evidence computaiton

Mr Luca Negri (Utrecht University)

The discovery of gravitational waves (GWs) has opened a new window to observe our universe which is inaccessible with other probes. Since 2015, almost 100 GW signals have been observed, allowing us to probe the nature of gravity, study the expansion of the universe as well as probe the equation-of-state of dense nuclear matter. Within the next decade, GW detectors are envisaged to undergo...

Neutrinoless double beta decay (0𝜈ββ) is an undetected rare nuclear process with significant implications for understanding the nature of neutrinos, their mass, and physics beyond the Standard Model. The most stringent limit on the 0𝜈ββ half-life is established by KamLAND-Zen, an extension of the KamLAND neutrino detector in Japan, utilizing the isotope xenon-136 dissolved in a liquid...

5. Preparing the AugerPrime Radio Detector for Ultra-High Energy Cosmic Ray Detection via Radio Interferometry.

The Pierre Auger Observatory, the largest cosmic ray experiment in the world, spans 3,000 km² and employs multiple detection mechanisms for ultra-high energy cosmic rays (UHECRs). Currently, the observatory is undergoing an upgrade to AugerPrime, which introduces a Radio Detector (RD) that enhances detection capabilities within a zenith angle range of 60 to 85 degrees. The RD offers a 100%...

6. Exploring Hadronic B-decays through SU(3) Flavor Symmetry

Marta Burgos (Maastricht University)

The decays of beauty mesons provide interesting opportunities to study CP violation, for which hadronic B-decays are excellent probes. However, the non-perturbative nature of hadronic decays poses significant challenges for theoretical predictions. To address these complexities, we employ SU(3) flavor symmetry, which assumes the quarks up, down and strange are equivalent under the strong...

11. Probing the Higgs self-coupling in the $HH\to b\overline{b}\gamma \gamma$ channel

Alexandra Sidley

Since its discovery in 2012, measurements of the properties and couplings of the Higgs boson have been at the forefront of LHC physics. The trilinear self-coupling of the Higgs boson $\lambda$ determines the shape of the Higgs potential, and deviations of its value from the Standard Model prediction may point to new physics. $\lambda$ can be probed experimentally via diHiggs (HH) production....

17. Sexaquarks: Quarks uniting to form Dark Matter at LHCb

Wouter Morren

08/11/2024, 12:20

The sexaquark, a neutral, flavour singlet scalar uuddss bound state, is a hypothetical particle that may have a low enough mass to be stable or extremely long-lived. Therefore, this hadron could be a DM candidate. In this talk, I will present what we know so far about the sexaquark, based on theoretical findings and astrophysical and cosmological observations. Using this knowledge, different...
