In this paper, we search for the baryon and lepton number violating charm decays, 𝐷→𝑝⁢ℓ, where ℓ is a muon or an electron. This decay mode is rare in the SM but can be enhanced if there is lepto-quark. Also, this decay mode provide same access to the New Physics as proton decay provides.  We searched for the muon modes for the first time in the world. In absence of negative result, we provided the world's best upper limit till now.

In this work, we search for rare decays and in absence of any significant signal we measure the world's most precise measurement till now. Our upper limits are 20 time more stringent than the previous measured.

Search for the Lepton Flavour violation in Upsilon(1S) decay. We provided the world's most precise measurement. Further, we search for the Radiative Lepton Flavour violation mode for the  first time in the world

In this work, we search for B -> Y(4260) K  decays  and in absence for any signal provided the world's most stringent upper limit.

Published in Phys. Rev. D Rapid Communications. 

In this work, we search  the exotic states X(3872) and X(3915) decays in B decays for the first time in Belle. Our limits agree with the BESIII measurement for the X(3872).
