Charmed meson production based on dipole transverse momentum representation in high energy hadron-hadron collisions available at the LHC / Sampaio dos Santos, G.  (Rio Grande do Sul U.) ; Gil da Silveira, G.  (CERN ; Rio Grande do Sul U. ; Rio de Janeiro State U.) ; Machado, M.V.T. (Rio Grande do Sul U.)
The production of $D$-mesons in high-energy $pp$ collisions at the LHC kinematic regime is analyzed with the dipole approach in the momentum representation. We present predictions for the $D$-meson differential cross section in terms of the transverse momentum and rapidity distributions taking into account the nonlinear behavior of the QCD dynamics. [...]

$D$-meson production in high energy $pA$ collisions within the QCD color dipole transverse momentum representation / Santos, G. Sampaio dos (Rio Grande do Sul U.) ; da Silveira, G. Gil (Rio Grande do Sul U. ; CERN) ; Machado, M.V. T. (Rio Grande do Sul U.)
The $D$-meson production is investigated by considering the unintegrated gluon distribution within the dipole approach in the momentum representation. We analyze the $D$-meson spectrum accounting for the effects of nonlinear behavior of the QCD dynamics which can be accordingly addressed in the dipole framework. [...]

A study on the isolated photon production in nuclear collisions at the CERN-LHC energies / Santos, G. Sampaio dos (Rio Grande do Sul U.) ; da Silveira, G. Gil (Rio Grande do Sul U., Porto Alegre (main) ; CERN) ; Machado, M.V.T. (Rio Grande do Sul U.)
An analysis of prompt photon production in high energy nuclear collisions at the LHC energy regime is performed within the parton saturation picture taking into account the updated phenomenological color dipole models. The results are confronted with the measurements made by the ALICE, ATLAS, and CMS experiments in terms of photon transverse momentum at different rapidity bins. [...]

Investigation of scalar and fermion dark matter in mono-photon production at high-energy colliders / da Silveira, G. Gil (CERN ; Rio Grande do Sul U.) ; Mateus, M.S. (Rio Grande do Sul U.)
Many theories about dark matter have emerged due to its strong theoretical appeal in explaining astrophysical phenomena. However, experimental and theoretical particle physics have yet not provided evidence that dark matter is part of the observable Universe. [...]

Nonexclusive particle production by $\gamma\gamma$ interactions in $pp$ collisions at the LHC / da Silveira, G. Gil (Rio Grande do Sul U. ; Rio de Janeiro State U.) ; Gonçalves, V.P. (Pelotas U.) ; Vargas Veronez, G.G. (Pelotas U.)
Particle production in two-photon interactions at hadronic collisions is becoming increasingly relevant in the LHC physics programme as a way to improve our understanding of the Standard Model and search for signals of New Physics. A key ingredient for the study of these interactions in $pp$ collisions is the description of the photon content of the proton, which allow us to derive predictions for the cross sections associated to events where occur the proton dissociation (non - exclusive processes) and for those where both incident protons remain intact (exclusive processes).

QCD probes at LHC / Da Silveira, G. Gil (Rio Grande do Sul U. ; Rio de Janeiro State U.) /ATLAS, CMS and LHCB Collaborations
The LHC experiments have reported new results with respect to the dynamics of the strong interactions in $pp$, $p$A, and AA collisions over the past years. In proton-proton collisions, the data analyses have focused in exploring the nature of underlying events and double parton scattering at high energies. [...]

Diffractive $\gamma \gamma$ production in $pp$ collisions at the LHC / Goncalves, V.P. (Pelotas U.) ; Martins, D.E. (Rio de Janeiro Federal U.) ; Rangel, M.S. (Rio de Janeiro Federal U.)
In this letter we estimate the contribution of the double diffractive processes for the diphoton production in $pp$ collisions at the Large Hadron Collider (LHC). The acceptance of the central and forward LHC detectors is taken into account and predictions for the invariant mass, rapidity and, transverse momentum distributions are presented. [...]

Exclusive vector meson production in electron – ion collisions at the EIC, LHeC and FCC–$eh$ / Goncalves, Victor P. (Pelotas U.) ; Martins, Daniel E. (Rio de Janeiro Federal U.) ; Sena, Celso R. (Pelotas U.)
The exclusive vector meson production in electron-ion collisions for the energies of the future colliders is investigated. We present predictions for the coherent and incoherent $\phi$ and $J/\psi$ production in $eAu$ collisions considering the possible states of nucleon configurations in the nuclear wave function and taking into account of the non-linear corrections to the QCD dynamics. [...]

Coherent and incoherent $J/\Psi $ photoproduction in $Pb - Pb$ collisions at the LHC, HE-LHC and FCC / Gonçalves, Victor P. (Pelotas U.) ; Martins, Daniel E. (Rio de Janeiro Federal U.) ; Sena, Celso R. (Pelotas U.)
The coherent and incoherent $J/\Psi$ photoproduction in $PbPb$ collisions are investigated considering the possible states of nucleon configurations in the nuclear wave function and taking into account of the non - linear corrections to the QCD dynamics. The cross sections and the rapidity and transverse momentum distributions are estimated for the energies of the next run of the LHC, High -- Energy LHC and Future Circular Collider. [...]
