1. An analysis on single and central diffractive heavy flavour production at hadron colliders
In this contribution results from a phenomenological analysis for the diffractive hadroproduction of heavy flavors at high energies are reported. Diffractive production of charm, bottom and top are calculated using the Regge factorization, taking into account recent experimental determination of the diffractive parton density functions in Pomeron by the H1 C

2. Medida da fração de eventos de dupla troca de Pomeron inclusiva em produção de dijatos centrais / Study on the fraction of double pomeron exchange in inclusive dijets.
This thesis presents the first DØ measurement of the fraction of Double Pomeron Exchange (DPE) in a central dijet production. An extensive study on the behavior of the energy deposited on the hadronic calorimeter cell was performed. In the search for DPE events the goal was to find gap (or low activity) in two forward calorimeter regions, which is a signatu

4. Study of diffractive production of top-anti-top at CMS/LHC / Estudos de produção difrativa de top-anti-top no CMS/LHC
Inclusive DPE (double pomeron exchange) production of t pairs was studied for CMS high luminosity running (2 x 1033cm-2s-1 ), with one top decaying into a b-jet, a muon and a neutrino, and the other to jets, one of them a b-jet (bbqqμνμ). The process was simulated with the generator DPEMC v2.4 [12], together with the fast CMS simulation code F

5. Hadronic physics in peripheral heavy Ion collisions
We discuss the production of hadronic resonances in very peripheral heavy ion collisions, where the ions collide with impact parameter larger than twice the nuclear radius and remain intact after the collision. We compare the resonance production through two-photon and double Pomeron exchange, showing that when we impose the condition for a peripheral intera
