"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.

First Z'->invisible task force meeting with international collaborators

Being members of the Belle II Collaboration, the analysis work on the main research topics of InterLeptons is a collaborative effort. Today, 25/11/2020, together with our international collaborators from INFN Roma3, Roma3 University, University of Naples, CPPM Marseille we met to discuss the search for the invisible decays of a Z' boson with data collected at Belle II. Such a search is one of the core topics of InterLeptons. During the meeting, that due to the covid-19 pandemic took place remotely via Zoom, we discussed the status and plans for the search of invisible decays of the Z' boson with Belle II data. The meeting was very useful to discuss and outline and the main ideas for the analysis sub-tasks to which each group will contribute. The team is mostly formed by the leading authors of our previous paper Phys. Rev. Lett. 124, 141801 (2020) with some new members joining and some leaving. A new journey has just started, Itterasshai!
