Research

I am studying bottomonia, a family of mesons composed of a bottom quark and an anti-bottom quark bound together in different energy states. The spin-0 partner of this family are known as η_b(nS), also η_b(1S) is the ground state of the bottomonium family. 'ϒ(nS)' mesons are spin-1 partners of this family, and they can be seen directly from the e+e- collision.

• Search for bottomonium states in the exclusive radiative ϒ (2S) decays (PhysRevLett.111.112001(2013)).
• Testing violation of "Lepton Universality in ϒ(1S) decays" in the data collected by Belle experiment at ϒ(2S) resonance.

More details coming soon...
