Origin of mass 

The Standard Model of particle physics is the most successful quantum theory of our Universe. There are different flavours of quarks and leptons whose masses are hierarchical and apparently free parameters of the theory.   Moreover, there is a  bizarre mixing among different flavour  of quarks as well as among different flavours of neutral leptons (neutrinos) whose origin is still unknown.  In short, we need to understand the origin of mass of the matter of our Universe.  This is called the  Flavour Problem of  the Standard Model.

We have proposed novel and original ideas to solve the Flavour problem of the Standard Model, and continuously exploring these ideas at experimental frontiers.  The related research articles are:
