1. Search for a heavy neutral lepton that mixes predominantly with the tau neutrino / Ori Israel Fogel ; Abner Soffer [BELLE2-MTHESIS-2023-016] Presented on 28 02 2023 MSc
Tel Aviv University / Tel Aviv
Heavy neutral leptons (HNLs) are highly motivated as a solution to the problems of neutrino masses, dark matter and the baryon asymmetry of the universe. [...]

2. Measurement of the branching fraction of $B^{0}\to D^{*-}l^{+}\nu_{l}$ with early Belle II data / Minakshi Nayak ; Abner Soffer ; Florian Bernlochner ; Lu Cao ; et al [BELLE2-CONF-PH-2020-002]
15 April 2020

We measure the branching fractions for the decays $B^{0}\to D^{*-}e^{+}\nu_{e}$ and $B^{*0}\to D^{*-}\mu^{+}\nu_{\mu}$ using the first $8.70 \pm 0.09 fb^{-}$ of data collected by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+ e^-$ collider using the decays $D^{*+}\to D^0 \pi^+$ and $D^0\to K^-\pi^+$..

3. Beam-constrained vertexing for B physics at the Belle II Experiment / Sourav Dey ; Abner Soffer [BELLE2-CONF-PROC-2019-017] this is the proceeding for submission based on the talk:
24 November 2019

The Belle II experiment, which recently began collecting $e^+e^-$ collision data, will extend the successful physics program of BaBar and Belle with a 30-fold increase in integrated luminosity and an improved detector. [...]
