Search for new phenomena in the Belle II data

Task 1.1 Detector performance assessment.
Study and enhance the Belle II performance in terms of track and vertex resolution, energy resolution, photon detection
efficiency, particle identification power, by implementing smart and innovative data reconstruction algorithms on the
pre-LS2 data set (5/ab).


Task 1.2 Precision CKM tests and searches for non-SM CP violation
Determination of the parameters of the Cabibbo-Kobayashi-Maskawa unitarity triangle (phi1, phi2, phi3, |Vcb|, |Vub|,
CP violation in B and charmed meson decays.


Task 1.3 Rare decays and test for lepton flavour non-universality
Radiative and electroweak B meson decays (B → K(*)ll, K(*)nn, Xsg), semitauonic and leptonic B decays (R(D(*)),
R(X)), tests of lepton flavour universality in B and tau decays


Task 1.4 Direct searches for light non-SM physics
Axions and axion-like particles, dark photon, Z’, long-lived signatures


Task 1.5 Quantum chromodynamics: Quarkonium, exotic and hadron spectroscopy (charmed baryons), constraining
hadronic vacuum polarization in g-2
