Abstract: Statistically significant di-photon excess at 95 GeV (~3sigma) and 152 GeV (>4sigma) have been observed. Furthermore, strong tensions exist between the SM predictions and measurements of W and top-like signatures at the LHC. I discuss the status of these anomalies, and how they can be related via new Higgses at the electroweak scale.

 

Andreas Crivellin is a SNSF Professor at University of Zurich and Paul Scherrer Institute, Switzerland in 2019. He received his Ph.D. from Karlsruhe Institute of Technology in 2013. After that, he was a postdoc at University of Bern and CERN before joining the SNSF Professorship. Also, he had a Scientific Associateship at CERN during 2020-2021. His main research area is physics beyond the Standard Model, with a particular focus on the flavour anomalies and the LHC anomalies. He has 110+ peer reviewed articles with 10 authors or less, including 16 of them published in Physical Review Letters. He is currently interested in growing evidences for new scalars at the electroweak scale.
