Some of the possible decays of pp collisions at LHC experiment are considered. The vector bosons mediating in the electroweak interactions and right-handed leptons except neutrinos are assumed to be the most resultant particles from the pp collisions. Neutrinos and anti-neutrinos will be observed when one-double electron charged vector bosons are the resultant particles. The charge conservation is thought to be the dominant factor of these decays. The amplitude transitions for Feynman diagram of these decays are written.
The Standard Model (SM) is in difficulties with defining the problems:
1) The Higgs particle mass,
2) Including the gravitational interactions to the SM,
3) The dark matter representation in the model,
4) The masses for neutrinos,
5) Large gap energy between electroweak scale and Planck scale,
6) The unification of gauge couplings of the electroweak interactions at some energy scale if the four fundamental forces are the result of a local gauge theory with a higher fundamental symmetry.
The recent experiments mainly LHC and the future colliders will solve these problems. The electromagnetic field interactions and weak interactions are combined in a single representation by the Glashow-Weinberg-Sa- lam Model of the electroweak interactions based on the gauge group SU(2) × U(1) which is in good agreement with the experimental results. Later the strong interactions are included to the theory and the group is written as SU(3)C × SU(2)L × U(1)Y. This group defines the SM particles. Since the four fundamental forces; weak, electromagnetic, strong, and gravity; are equal at the Grand Unified Theory (GUT) energy scale, the some of the additional neutral gauge bosons might be discovered at CERN LHC experiment as well as the lightest supersymmetric stable particle of the dark energy and the particles which have at the same time the properties of the leptons and quarks or the states changes to each other named as lepto-quarks or exotic fermions. The fermionic particles of the SM are grouped in the representation of the three generations as
The first two particles of each group are the leptons with charges 0, –1 respectively in the unit of the electron charge. The last two are quarks with the electron charge +2/3 and –1/3 for u and d type quarks. Each particles described have their anti-particles. These particles all together build up the matter around us.

Using the conservation of the protons’ charges, some of the possible pp collisions decays will be such that (
When it is assumed that the anti-leptons are the resultant particles as the vector bosons then the right-handed neutrinos couldn’t be seen as the resultant particles. In these decays instead of the intermediate vector bosons the neutral and plus-charged Higgs bosons could take the place. The Higgs bosons would be the plus ones replaced in the resultant particles such that

Since the protons have the same 4-momentum it is true to write down:
Therefore, the exponential term not written in Eqn. (10) is 1. The scattering amplitude can be written as

Although the SM has some difficulties, it is strongly a correct model to extend at the GUT scale. By using the previous works the W' gauge boson mass is estimated to be around 498 GeV. The resultant particles from pp collisions are assumed to be a double positive-electron charged vector boson with a neutrino or anti-neutrino, or, two vector bosons each with one positive-electron charge, instead of the latter one; two anti-leptons are also accepted except the neutrinos. The pp collisions at GUT scale will give the scattering amplitudes as done in this work.
