1. Estudo sobre a identificação de hádrons em câmaras de fotoemulsão / Study about hadron identification in emulsion chambers
This work introduces the importance of photoemulsion chambers that remain in use after decades and still offer many advantages for elementary particle physics. We cite OPERA (Oscillation Project with Emulsion-tRacking Apparatus) detector that is the greatest lead photoemulsion chamber detector ever constructed as an example of its application nowadays (nine

2. Transições de fase hádron-quark em estrelas de nêutrons
Recent advances on the field of high energy physics have enabled the study of matter under extreme conditions and, in this context, new states of matter are being discovered and speculated upon. Among these hypothetical states of matter is the one of deconfined quarks in high densities and/or temperatures. An environment with extreme densities and low temper

3. O vértice D*Dp usando as regras de soma da QCD / The D*Dp vertex using the QCD sum rules
The particle physics have been studying topics like the Quark-Gluon Plasma (QGP), Higgs boson and dark matter, which require experiments in heavy-ion collisions. Therefore, accelerators capable of generate high energy particle beams are necessary and may generate new physics. When new data arise in the laboratories, new processes are necessary to explain thi

4. On the inverse problem in high-energy elastic hadron scattering and the applicability of a representation for the real part of the amplitude / Um estudo sobre o problema inverso do espalhamento elastico de hadrons em altas energias e a aplicabilidade de uma representacao para a parte real da amplitude
The theoretical description of high-energy elastic hadron scattering constitutes an open problem in both, the underlying quantum field theory of strong interactions (QCD) and the phenomenological context. In this work the inverse problem in elastic hadron scattering is discussed in the impact parameter and eikonal frameworks, specifically a study on the empi

5. Forward Physics at the LHC: within and beyond the Standard Model
We review the detection capabilities in the forward direction of the various LHC experiments together with the associated physics programme. A selection of measurements accessible with near-beam instrumentation in various sectors (and extensions) of the Standard Model (SM) is outlined, including QCD (diffractive and elastic scattering, low-x parton dynamics,

6. Gauge/string duality and hadronic physics
We review some recent results on phenomenological approaches to strong interactions inspired in gauge/string duality. In particular, we discuss how such models lead to very good estimates for hadronic masses.

7. Charmless hadronic penguin B decays with BaBar: B0$B^0(\overline{B}^0)\rigtarrow \overline{K}^0}K^0$K0 or h¢ h¢
Recent results from the BaBar experiment on searches for New Physics using the charmless channels B0 -> $\overline{K}^0}K^0$K0 and B0 ® h¢ h¢ are discussed.

8. Medida da fraÃÃo de eventos de dupla troca de Pomeron inclusiva em produÃÃo de dijatos centrais. / Study on the fraction of double pomeron exchange in inclusive dijets.
This thesis presents the first DÃ 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

10. Nucleon resonance excitation with CLAS
The study of the baryon spectrum is a fundamental part of the scientific program in Hall B at Jefferson Laboratory. The so called N* program indeed concerns the measurement of the electromagnetic production of exclusive hadronic final states, with the purpose of extracting information on baryon excited states. CLAS, the CEBAF Large Acceptance Spectrometer, i

11. JLab: probing hadronic physics with electrons and photons
Precision measurements of the structure of nucleons and nuclei in the regime of strong interaction QCD are now possible with the availability of high current polarized electron beams, polarized targets, and recoil polarimeters, in conjunction with modern spectrometers and detector instrumentation. The physics at JLab will be highlighted using two recent meas
