"A search for new interactions at Belle II using leptons"

This is the official page of the research team "InterLeptons" at the High Energy Physics Institute of the Austrian Academy of Sciences. The team, led by Dr. Gianluca Inguglia, is funded under the grant agreement nr. 947006 of the Starting Grant award offered by the European Research Council (ERC). The research activities of the team will be described and kept up-to-date on these pages.
The aim InterLeptons is to unveil the new physics nature of the so-called flavor anomalies implementing a bottom-up approach based on the studies of data collected at the Belle II experiment, located in the interaction region
of the Super-KEKB collider. The team focuses on final state events containing leptons and a large amount of missing energy. The results of the searches will be interpreted in terms of low mass dark matter, new forces/interactions, and in terms of lepton flavor violating and lepton flavor non-universal couplings.

InterLeptons brings a significant advancement of a new research area in Austria with the potential of revolutionizing particle physics.

Dark matter day 2022

Members of the InterLetons group have organized and participated in the Dark Matter Day 2022, a global outreach event aimed to raise awareness about and engage the general public with research on dark matter. In Vienna, the event took place at the WUK on October 31st.
We are very interested in the topic, in fact, as researchers of the Belle and Belle II experiments, we are involved at various levels in the coordination of many Dark Matter searches in both the experiments.
At the Dark Matter Day 2022 we contributed with the installation of the Belle II Virtual Reality (Paul Feichtinger) and a presentation about possible ways to search for Dark Matter (Nadia Maslova). In her presentation, Nadia focused the audience's attention to her current main topic, the search of B decays to final states involving large amounts of missing energy, such as B->Knunu. This specific decay is of interest not only because it relates to other b-to-s transitions in which anomalies have been observed; but also because, given the presence of missing energy in the final state, dark matter could produce this. The event was successful, and InterLeptons group members enjoyed discussing about the InterLeptons project in a very relaxed atmosphere.
