vacuum quantum numbers of the exchanged particle: the Pomeron. It means that the final state has a particular rapidity distribution, where the rapidity range between the colliding particles is free of secondary particles, i.e., there is no production of particles in this region, only the Higgs. However, the rapidity gaps predicted theoretically are bigger than those observed in the experimental results. This contradiction occurs due to the still poor theoretical description of the interactions occuring by the presence of secondary particles. The mechanism that provides the correct prediction of the rapidity gaps is the Rapidity Gap Survival Probability (GSP), which accounts for the probability that, during a process, the rapidity gap will survive to interactions with the spectator particles. In other words, the GSP is the probability that will have an event where does not occur other interactions except the hard collision. Thus, a multiplicative factor $S^{2}_{gap}$ is included in Eq.(\[final-eq1\]), which will account for the reduction of the predicted cross section, reaching the correct value expected to be measured in the laboratory.

The survival probability was originally formulated by Bjorken [@bjorken1993] as $$\begin{aligned}
S^{2}_{gap} = \frac{\int d^{2}b \, \Gamma_{H} (b) \, | P(s,b) |^{2}}{\int d^{2}b \, \Gamma_{H}(b)},\end{aligned}$$ where $\Gamma_{H}(b)$
