FH Particle Physics Pizza seminar - Valentina Cairo

Monday 8 May 2023, 11:30 → 13:00 Europe/Berlin

SR 3 (DESY Hamburg)

Aaron Dean Spector (DESY), Claudia Seitz (DESY), Juergen Reuter (DESY)

The goal of the FH Particle Physics Pizza seminar is to foster discussion and exchange between the various FH physics groups at DESY. Specifically, we are trying to enhance the exchange between the experimental and theory community, with in-depth talks about a specific topic in a more informal setting. 
 

We will order pizza (vegetarian and meat options with cheese) to eat for lunch. In order to have a better estimate of how many people come, please click on the "Register" link below. 

 

We will collect 7 Euros from every participant who registers and wants to eat some pizza. If you have any specific food requirements (vegan, gluten free, etc.) please let us know in advance and we will see what we can do. If a reference paper exists, we will link it from the page and encourage you to read it before the seminar. 

 

If you do not want pizza (or the limit of 25 people has been reached for food), you do not need to register, just join us in the seminar.

11:30 → 12:10 The missing pieces in the Higgs Puzzle at the LHC and Beyond

The post-Higgs discovery era has been characterized by an exciting physics programme targeting the investigation of the Higgs boson properties and couplings. Amongst the crucial yet-to-be answered questions in Particle Physics arethe shape of the Higgs potential and the nature of the Higgs Yukawa couplings.
Probing the Higgs self-coupling, which determines the shape of the Higgs potential and is directly connected to the electroweak symmetry breaking mechanism, is one of the most important goals of the High-Luminosity phase of the Large Hadron Collider (LHC) experiments. Higgs decay modes to light quarks, instead, are key to investigate the universality of the Yukawa couplings but they are very challenging or nearly impossible to detect with the current experiments at the LHC. A future e+e- collider is thus the perfect avenue to pursue this research.
The first part of this talk will describe the current results and the future projections of direct tests of the Higgs self-coupling via Higgs pair production with the ATLAS experiment at the LHC. The second part will be dedicated to the development of novel algorithms at future e+e- colliders for tagging jets originating from the hadronisation of strange quarks (strange-tagging) and the first application of such a strange-tagger to a direct Higgs to strange (H->ss) analysis with the ILD Concept Group at the International Liner Collider. The study includes a preliminary investigation of a Ring Imaging Cerenkov system (RICH) capable of maximising strange-tagging performance in future Higgs factory detectors.
