              In this research we studied the experimental from Large Hadron Collider (LHC) in European Organization for Nuclear Research (CERN) Laboratory, to find out “what happens in the first 3 seconds of origin of the universe?”.  In this work, the program was written in C language to calculate the cross section values which showed the possibility for create Charm Quark and Anticharm Quark in the colliding interactions of Up Quark and Anti-up Quark from the two proton beams.The quantity and types of particles related to cross section values and the momentum values would make us understand the forms and patterns of particles that took place. Based on the study, it was found that there was very little mass of  colliding particles , and that meant kinetic energy or momentum of up quark colliding with anti-up quark had to have enough values to recombine with its own mass before forming Charm Quark and Anticharm Quark. The suitable values of both kinetic energy and momentum would be in the range of 2200  MeV/c^2; at other values, it was less likely that the particles would form. Besides, in the written program, the direction of particle collisions was predetermined; and since the value of  phe angle was zero, the cross section value obtained was only the function of  zeta  angle; and for the suitable scattering angle,the particle formed is likely to scatter in the direction that the particle comes in or  scatter  to  opposite direction.
