Shakeel Mahmood, Farida Tahir, Azeem Mir
TL;DR
This paper investigates how second-generation quarks influence non-standard interactions (NSIs) via rare meson decays with neutrinos, providing new constraints on NSI parameters through analysis of FCNC processes.
Contribution
It introduces the role of second-generation quarks in NSIs and constrains NSI parameters using rare meson decay processes involving neutrinos.
Findings
C and s quarks can affect NSIs similarly to u and d quarks.
Constraints on NSI parameters are derived from six FCNC semi-leptonic meson decays.
Second-generation quarks play a significant role in NSI phenomenology.
Abstract
We study the contribution of 2nd generation of quarks in NSIs. We investigate it through the rare decays of mesons involving neutrinos in the final state. We show the C and s quarks can effect NSIs just like u and s. We explore constraints on free parameter of NSIs. For this purpose we select 6 FCNC semi-leptonic processes of B, D and K mesons having neutrinos in the final state
