The LHC as an Axion-Photon Collider
Sergio Barbosa, Matheus Coelho, Sylvain Fichet +2
Assuming the existence of an axion-like particle (ALP), beams of relativistic particles emit fluxes of quasi-real ALPs, analogous to the photon fluxes described by Weizsäcker-Willi…
Brazilian Report on Dark Matter 2024
I. F. M. Albuquerque, J. Alcaniz, A. Alves +51
One of the key scientific objectives for the next decade is to uncover the nature of dark matter (DM). We should continue prioritizing targets such as weakly-interacting massive pa…
Double charmed meson production in and collisions at the LHC within the dipole approach in momentum representation
G. Sampaio dos Santos, G. Gil da Silveira, M. V. T. Machado
A study of double charmed meson production in proton-proton and proton-nucleus collisions at the LHC energies is performed. Based on the color dipole formalism developed in the tra…
Searching for a Leptophilic Z' and a 3-3-1 symmetry at CLIC
A. Alves, G. Gil da Silveira, V. P. Gonçalves +3
We derive the discovery potential of a leptophilic Z', and a Z' rising from a symmetry at the Compact Linear Collider (CLIC), which is planned…
Investigation of spin-dependent dark matter in mono-photon production at high-energy colliders
G. Gil da Silveira, M. S. Mateus
Many theories about dark matter have emerged due to its strong theoretical appeal in explaining astrophysical phenomena. However, experimental and theoretical particle physics have…
-meson production in high energy collisions within the QCD color dipole transverse momentum representation
G. Sampaio dos Santos, G. Gil da Silveira, M. V. T. Machado
The -meson production is investigated by considering the unintegrated gluon distribution within the dipole approach in the momentum representation. We analyze the -meson spec…
Charmed meson production based on dipole transverse momentum representation in high energy hadron-hadron collisions available at the LHC
G. Sampaio dos Santos, G. Gil da Silveira, M. V. T. Machado
The production of -mesons in high-energy collisions at the LHC kinematic regime is analyzed with the dipole approach in the momentum representation. We present predictions…
Non-exclusive particle production by interactions in collisions at the LHC
G. Gil da Silveira, V. P. Goncalves, G. G. Vargas Veronez
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 St…
Prompt photon production in high-energy collisions at forward rapidity
G. Sampaio dos Santos, G. Gil da Silveira, M. V. T. Machado
Prompt photon production in hadronic collisions at the RHIC and the LHC energies is investigated within the QCD color dipole approach. Predictions for the nuclear modification fact…
Exclusive vector meson photoproduction at the LHC and the FCC: A closer look on the final state
G. Gil da Silveira, V. P. Goncalves, M. M. Jaime
Over the past years the LHC experiments have reported experimental evidences for processes associated to photon-photon and photon-hadron interactions, showing their potential to in…
