Measurement of the time-integrated mixing probability with a semileptonic double-tagging strategy and of Belle II collision data
Belle II Collaboration, F. Abudinén, I. Adachi +550
We present the first measurement of the time-integrated mixing probability using Belle II data collected at a center-of-mass (CM) energy of 10.58 GeV, corresponding to the ma…

Search for an invisibly decaying boson at Belle II in plus missing energy final states
Belle II Collaboration, I. Adachi, P. Ahlburg +358
Theories beyond the standard model often predict the existence of an additional neutral boson, the . Using data collected by the Belle II experiment during 2018 at the…
