Hilbert Series of Pseudoscalar Mesons: Operators and Sum Rules
Joydeep Chakrabortty, Sabyasachi Chakraborty, Siddhartha Karmakar
We construct the complete non-redundant basis of operators built from pseudoscalar mesons using the Hilbert series method, subject to the global flavor symmetry $SU(3)_L \times SU(…

A Phenomenological Model of Mesons for Charged Current Weak Decays
Sabyasachi Chakraborty, Namit Mahajan, Tuhin S. Roy
We propose a phenomenological model of pseudo scalar mesons to describe charged-current weak decays of heavy-light mesons. The approach combines chiral symmetry in the light sector…

Anomaly induced cooling of Neutron Stars: A Standard Model contribution
Sabyasachi Chakraborty, Aritra Gupta, Miguel Vanvlasselaer
Young neutron stars cool via the emission of neutrinos from their core. A precise understanding of all the different processes producing neutrinos in the hot and degenerate matter…
