Abstract:
The sensitivity of the D0-D0 mixing parameters x and y is estimated in the wrong-sign decay D0→K+π-π0 by time-dependent amplitude analysis. The resolution of the D0 lifetime is essential in time-dependent Dalitz analyses. The Belle Ⅱ detector, which ...

We explore the discovery potential of Higgs pair production at a 100 TeV collider via full leptonic mode. The same mode can be explored at the LHC when Higgs pair production is enhanced by new physics. We examine two types of fully leptonic final sta...
