Description
Suman Baral Computation of the Octet Baryon Isomultiplet Mass Splittings

One of the major facts that govern the stability of atoms is the slight mass difference between neutrons and protons, neutrons being the massive one. Similarly, when quark mass difference effects on octet baryon masses are small, one can see interesting results. Stability of hydrogen atom against beta decay is a good example. Authors have included such effects by adding them to valence quarks in a lattice QCD calculation and were able to acquire authority over most of the systematic errors and the outcome for the total splitting is compatible with experiment. In my presentation I will try to explain these results in detail.
