Abstract
The exclusive decays of the Higgs boson into  and  mesons are being studied using the fragmentation approach. One of the dominant modes of the Higgs boson decay in the Standard Model is its decay into  pairs, which then directly decay into   and  mesons. In this article, the branching ratio and decay widths of the SM Higgs boson to the  and  mesons have been calculated by directly fragmenting the anti-quark  within the framework of perturbative Quantum Chromodynamics (pQCD) at leading order (LO). The results of these calculations are in very good agreement with those obtained by other authors.
