Probing the X(3700) through two-photon $D D ˉ$ production in ultraperipheral collisions and at the EIC

F. C. Sobrinho, F. S. Navarra, K. P. Khemchandani +1

We investigate whether photon-induced production in ultraperipheral heavy-ion collisions and at the EIC can provide a new environment to search for the scalar $D D ˉ$ molecular…

Probing the $G (3900)$ State in Heavy-Ion Collisions

Luciano M. Abreu, Pedro Brandão, Rodrigo O. Magalhães +1

We investigate the interactions of the recently confirmed exotic hadron $G (3900)$ with the hadronic medium composed of light mesons produced in heavy-ion collisions. Using an effec…

Effects of the magnetic field on $π^{0}$ production in ultraperipheral Pb-Pb collisions

C. N. Azevedo, R. Fariello, F. C. Sobrinho +1

In this work, we study the effect of the magnetic field on the production of neutral pions in photon-photon interactions in ultraperipheral Pb-Pb collisions at the LHC. The calcula…

Effects of the initial-state geometry on D-meson production in pp and pPb collisions

R. Terra, A. V. Giannini, F. S. Navarra

Going from lower to higher multiplicity events in proton-proton and proton-lead collisions, the data show a stronger than linear growth of the D-meson normalized yields. In this co…

Charm multiplicity distribution in high energy pp collisions with PYTHIA

Y. N. Lima, C. Jahnke, M. Munhoz +1

With the growth of statistics in the future experiments at the LHC, the number of events with charm production will increase substantially. It may become possible to measure the mu…

The sharpness of the quark-hadron transition and the properties of hybrid stars

M. B. Albino, R. Fariello, G. Lugones +1

We investigate the effects of the sharpness of the phase transition between hadronic matter and quark matter on various properties of neutron stars. We construct hybrid equations o…

Interactions of the deuteron with a hadronic medium

L. M. Abreu, R. Higa, R. O. Magalhães +1

We investigate the interactions of the deuteron with light mesons during the hadronic phase in heavy-ion collisions. We treat the deuteron as a weakly bound state and employ the qu…

Initial-state geometry and multiplicity distributions in pp and pPb collisions

R. Terra, A. V. Giannini, F. S. Navarra

This work investigates the possibility of accessing the initial geometric shape of the proton in proton-proton and proton-nucleus collisions at the LHC. In particular, we look for…

Multiplicity Distributions and the Frontier between Soft and Hard Physics

H. R. Martins-Fontes, F. S. Navarra

The multiplicity distributions measured in proton proton collisions at the LHC exhibit interesting new features. One of them is the appearance of substructures, such as the so-call…

Soft and semihard components of multiplicity distributions in the $k_{T}$ factorization approach

H. R. Martins-Fontes, F. S. Navarra

Particle production in hadronic collisions can be studied in the low-momentum (soft) and high-momentum (hard) transfer regimes. While the latter can be well understood with in pert…

Universality of scaling entropy in charged hadron multiplicity distributions at the LHC

L. S. Moriggi, F. S. Navarra, M. V. T. Machado

In this work, we investigate the scaling behavior of the entropy associated with the charged hadron multiplicity distribution P(N) in proton-proton collisions at the LHC. We show t…

Production of $η_{b}$ in ultra-peripheral $P b P b$ collisions

C. N. Azevedo, F. C. Sobrinho, F. S. Navarra

Very recently, the two-photon decay width of the $η_{b}$ meson was computed with lattice QCD methods. This decay has not yet been measured. The knowledge of this width allows for the…

Studying the nature of the lightest charmed axial mesons via femtoscopy

Luciano M. Abreu, Kanchan P. Khemchandani, Alberto Martínez Torres +1

In this work we discuss how femtoscopic analysis can shed light on the nature of the two lightest axial charmed mesons, denominated as $D_{1} (2430)$ and $D_{1} (2420)$ , whose masses are…

Hadronic scattering effects on $ψ (2 S)$ suppression in relativistic heavy-ion collisions

L. M. Abreu, F. S. Navarra, H. P. L. Vieira

In this work we estimate the $N_{ψ (2 S)} / N_{J / ψ}$ yield ratio in heavy-ion collisions, considering the interactions of the $ψ (2 S)$ and $J / ψ$ states with light mesons in the hadro…
