Abstract: Energetic particles (mostly charged) radiations with energy ranging from ~ 106 eV to gt 1020 eV impinging continuously in the earth atmosphere from outer space are known as the Cosmic Rays (CR). The study of CR, especially in Ultra High Energy (UHE) range (gt 1017 eV) opens some important fields of research in the astronomy and particles physics. Interactions of Ultra High Energy Cosmic Rays (UHECR) in the atmosphere continuously develop a number of possible pro-cesses, of which some of them may lead to the production of different short-lived heavy particles. These might include some dicovered and undiscovered epoch changing particles which have a par-ticular significance in the world of physics. In resemblance of interactions, the detection of CR in this range is also a subject of great challenge and worth noting. It is entirely based on the indirect method of detection by measuring different measurable parameteres of EAS, produced by primary partices in the atmosphere, with a very large ground based detectors array. Both, the study of in-teraction processes for the production of heavy short-lived particles and the detection of UHECR are relied heavily on the detailed Monte Carlo (MC) simulation of the processes responsible for concerned particles production and development of EAS respectively, with the help of a realiable physical model. Thus MC simulation is a powerful and essential numerical method for the study of CR in general by virtually producing complete course of development of a CR event in the same manner as the real event. In this work, the first part incorporates the study of the production of Standard Model (SM) Higgs boson in UHECR interactions with air nuclei. Higgs boson is the most significant, but undis-covered component of SM. Here we developed and discussed a new approach for the observation of production of SM Higgs boson in UHECR interactions, based on the idea that, during UHECR interactions with air nuclei, this scalar particle is produced through vacuum excitation due to a fraction of...
