Fully-heavy tetraquarks in the vacuum and in a hot environment
VinÃcius S. Silva, Cássio Pigozzo, Luciano M. Abreu
We study the thermal behavior of quarkonia and fully-heavy tetraquark states associated to the charmonium, bottomonium and bottom-charmonium mass spectra. The starting point is the…

Dark sector interactions in light of weak lensing data
M. Benetti, P. T. Z. Seidel, C. Pigozzo +3
The current observational tensions in the standard cosmological model have reinforced the research on dynamical dark energy, in particular on models with non-gravitational interact…
