Mitigating Detector Ageing Effects with Graph-Based Multi-Modal Track Reconstruction at Belle II
Lea Reuter, Tristan Brandes, Giacomo De Pietro +1
Large backgrounds that can lead to hardware failures and the degradation of detector gain impact the track finding in the Belle II central drift chamber. These conditions lead to s…
Searches for charged-lepton-flavor violation in decays
Belle, Belle II Collaborations, : +425
We report the first searches for charged-lepton-flavor violation in decays of ( and ) to a pair of charged leptons using 158 million decays collect…
Measurement of time-dependent violation parameters in decays at Belle and Belle II
Belle, Belle II Collaborations, : +416
We perform a measurement of time-dependent violation parameters in decays using a dataset of approximately and $521 \times 10…
Kink Finder at Belle II
Denis Bodrov, Xinping Xu, Dmitrii Gavrilov +27
We present a track-finding algorithm for the Belle II experiment that specifically targets so-called kinks: signatures of charged particles decaying or scattering in-flight in the…
Study of at Belle II
Belle II Collaboration, M. Abumusabh, I. Adachi +404
The bottomonium spectrum, consisting of bound states of a quark and an anti- quark, provides an excellent laboratory for probing quantum chromodynamics in the non-perturbati…
Multi-Modal Track Reconstruction using Graph Neural Networks at Belle II
Lea Reuter, Tristan Brandes, Giacomo De Pietro +1
High backgrounds and detector ageing impact the track finding in the Belle II central drift chamber, reducing both track purity and track efficiency in events. This necessitates th…
