The presence of Vector-Like Quarks (VLQ) is introduced as one of the candidates for extending physics beyond the standard model explaining the hierarchy problem. Search for VLQ will provide valuable input for evaluating many underlying models that explain the stabilization of the Higgs boson mass, offering a potential solution to the hierarchy problem, and so on. A dedicated analysis for the...

3. Search for a single-produced Vector-Like Quark T’ decaying into a top quark and a Higgs boson in the dileptonic same sign final state for the full Run 2 data with the CMS experiment

One of the most challenging problems of the Standard Model (SM) is the mass of the Higgs boson that diverges by taking the loop contributions into account. The decay of new particles like Vector-Like Quarks (VLQs) could be an interesting explanation as the final state in SM particles is well understood. We will present here the decay of a VLQ T' into a quark top and a Higgs boson in a...

4. Systematic investigations for the presence of quark matter in neutron star cores

The nature of the fundamental degrees of freedom of the strong interaction at suprasaturation densities, reachable in the core of massive compact stars, is the subject of a large debate. While ab initio nuclear physics calculations provide substantial constraints on the equation of state at low densities, the presence of deconfined quark matter at larger densities, as hinted by perturbative...

5. Charged-particle pseudorapidity density in proton-proton collisions in ALICE Run 3 using MFT

Sarah Herrmann (IP2I Lyon)

Charged-particle pseudorapidity density measurements help to understand the particle production mechanisms in high-energy hadronic collisions, from proton-proton to heavy-ion systems. Performing such measurements at forward rapidity, in particular, allows one to access the details of the phenomena associated with particle production close to the fragmentation region of the colliding nuclei. In...

6. Dark-Sirens : How to explore the cosmology with gravitational waves

Grégoire Pierra (CNRS Ip2i Ondes gravitationnelles)

The LIGO-Virgo-Kagra (LVK) collaboration has detected 90 gravitational-wave (GW) events since September 2015, over three observing runs. These GW events can be used to infer the cosmological parameters of our Universe and peculiarly the Hubble constant H0. The Hubble constant is constrained using the luminosity distance estimated from each GW signals of compact binary coalescence, combined...
