WG5: Physics with Heavy Flavours

We report the measurements of gamma gamma ―> eta_c(1S), eta_c(2S)―>eta' pi+ pi- with eta' decay to gamma rho and eta pi+ pi- using 941 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. First observation of eta_c(2S)―>eta' pi+ pi- with a significance 5.5 \sigma including systematic error is obtained. The products of the two-photon decay width and...

WG5: Physics with Heavy Flavours

We report some of the most recent results in studying different aspects of QCD with about 500 fb$-1$ of data collected by the BaBar experiment at the $e^{+}{e}^{-}$ $B$-factory PEP-II.
Among these, we present a high precision measurement of the mass difference between the $D^{\ast }(2010{)}^{+}$ and $D^{+}$ mesons using the decay chain $D^{\ast }(2010{)}^{+}\to D^{+}{\pi }^0$, with $D^{+}\to K^{-}{\pi }^{+}{\pi }^{+}$. This...

K->pinunu is one of the theoretically cleanest meson decay where to look for indirect effects of new physics complementary to LHC searches. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the K+->pi+nunu decay with 10% precision. NA62 took data in 2015-2017; the analysis of a partial data set allows to reach the Standard Model sensitivity. The status of the...

247. Study of tau neutrino production property with measuring open-Charms at 400 GeV proton beam dump

WG5: Physics with Heavy Flavours

The property of tau neutrino is not well known, due to difficulty of its production and detection.
The comparison of the neutrino-nucleon cross-section of tau neutrinos and other neutrino flavours is one of the interesting topics.
The tau neutrino cross-section has been measured by the DONUT experiment, but with a large statistical error of $\sim 30\mathrm{\%}$ and a systematical uncertainty of...
