New graph-neural-network flavor tagger for Belle II and measurement of in decays
Belle II Collaboration, I. Adachi, L. Aggarwal +413
We present GFlaT, a new algorithm that uses a graph-neural-network to determine the flavor of neutral mesons produced in decays. It improves previous algorithms by usin…

Search for a heavy neutral lepton that mixes predominantly with the tau neutrino
Belle Collaboration, M. Nayak, S. Dey +165
We report a search for a heavy neutral lepton (HNL) that mixes predominantly with . The search utilizes data collected with the Belle detector at the KEKB asymmetric energy $e…
