Uma dedução alternativa às transformações de Lorentz e o relativismo do tempo na relatividade restrita
Peccini, Guilherme Müller (2015) [Trabalho de conclusão de graduação]No presente trabalho serão discutidas as Transformações de Lorentz e o Paradoxo dos Gêmeos. Em relação `as transformações, estas serão deduzidas levando-se em consideração apenas o Princípio da Relatividade, a isotropia ... -
Dilepton production through timelike compton scattering within the kT-factorization approach
Peccini, Guilherme Müller; Moriggi, Lucas Soster; Machado, Magno Valério Trindade (2020) [Artigo de periódico]In this work we consider the dilepton production via timelike Compton scattering (TCS) in electronproton and proton-proton collisions. In particular, the differential cross section in terms of the dilepton invariant mass ... -

Exclusive dilepton production via timelike Compton scattering in heavy ion collisions
Peccini, Guilherme Müller; Moriggi, Lucas Soster; Machado, Magno Valério Trindade (2021) [Artigo de periódico]In the present work, kT -factorization formalism is applied to compute the exclusive dilepton production by timelike Compton scattering (TCS) in eA, pA, and AA collisions. The nuclear effects are investigated considering ... -
Exclusive processes described by QCD at electron-ion colliders
Peccini, Guilherme Müller (2022) [Tese]In this work we aim to investigate electron-ion collisions, a highly important type of process with huge potential to deeply study the structure of matter. In particular, three processes that involve eA collisions are ... -
Exclusive Z0 production in ep and eA collisions at high energies
Peccini, Guilherme Müller; Machado, Magno Valério Trindade; Moriggi, Lucas Soster (2022) [Artigo de periódico]In this work the k⊥-factorization formalism is applied to compute the exclusive Z0 boson photoproduction in ep and eA collisions. The study is also extended to pp and AA processes. The nuclear effects are investigated ... -
A fenomenologia de dipolos de cor e a física de saturação em processos soft no regime de altas energias
Peccini, Guilherme Müller (2019) [Dissertação]Neste trabalho investigamos as interações hadrônicas soft usando o formalismo de saturação partônica relativo a evolução não-linear da QCD (Cromodinâmica Quântica), em conjunto com a teoria de Regge, a qual e o formalismo ... -
Investigating the diffractive gluon jet production in lepton-ion collisions
Peccini, Guilherme Müller; Moriggi, Lucas Soster; Machado, Magno Valério Trindade (2020) [Artigo de periódico]We study the diffractive jet production in electron-ion collisions in the kinematic region where the mass MX of the diffractive final state is larger than Q2. Based on parton saturation framework, predictions are done for ... -
Investigating the inclusive transverse spectra in high-energy pp collisions in the context of geometric scaling framework
Moriggi, Lucas Soster; Peccini, Guilherme Müller; Machado, Magno Valério Trindade (2020) [Artigo de periódico]The presence of geometric scaling within the pT spectra of produced hadrons at high energy pp collisions using small-x kT-factorization is investigated. It is proposed a phenomenological parameterization for the unintegrated ... -
Role of nuclear gluon distribution on particle production in heavy ion collisions
Moriggi, Lucas Soster; Peccini, Guilherme Müller; Machado, Magno Valério Trindade (2021) [Artigo de periódico]The transverse momentum spectra of hadrons are calculated from the unintegrated gluon distribution (UGD) within the kT-factorization framework at small x. Starting from pp collisions, the modification caused by the nuclear ... -
Soft diffraction within the QCD color dipole picture
Peccini, Guilherme Müller; Nóbrega, Fábio Köpp; Machado, Magno Valério Trindade; Fagundes, Daniel Almeida (2020) [Artigo de periódico]In this work we consider the QCD parton saturation models to describe soft interactions at the high energy limit. The total and elastic cross sections, as well as the elastic slope parameter, are obtained for proton-proton ...
