Coulomb corrections to inclusive cross sections at the future Electron - Ion Collider
The experimental results of the future electron -- ion () collider are
expected to constrain the dynamics of the strong interactions at small values
of the Bjorken -- variable and large nuclei. Recently it has been suggested
that Coulomb corrections can be important in inclusive and diffractive
interactions. In this paper we present a detailed investigation of the impact
of the Coulomb corrections to some of the observables that will be measured in
the future collider. In particular, we estimate the magnitude of these
corrections for the charm and longitudinal cross sections in inclusive and
diffractive interactions. Our results demonstrate that the Coulomb corrections
for these observables are negligible, which implies that they can be used to
probe the QCD dynamics.Comment: 9 pages, 6 figures. Improved version to be published in Physical

Coherent and incoherent production of vector mesons in ultraperipheral collisions of Xenon-ions within the QCD parton saturation approach
In this paper we analyse the exclusive vector meson photoproduction in the
recent run using Xenon-ions at energy of 5.44 TeV performed by the Large Hadron
Collider. We focus on the ultraperipheral collisions and provide theoretical
predictions for coherent and incoherent cross sections within the color dipole
approach and gluon saturation framework. The rapidity distribution is
investigated in both cases and comparison to other approaches available at
literature is done. We show that the expected yields are enough to perform
reliable cross section measurements for light mesons as and .Comment: 6 figures, 7 pages, accepted to be published in PRD. arXiv admin

Hard gluon evolution in the last stage of the bottom-up thermalization
The study of how fast thermalization in heavy ion collisions occurs has been
one of the central topics in the heavy ion community. In the weak coupling
picture this thermalization occurs from 'the bottom up': high energy partons,
formed early in the collision, radiate low energy gluons which then proceed to
equilibrate among themselves, forming a thermal bath that brings the high
energy sector to equilibrium. In this scheme we apply a model on parton energy
loss to discuss the effects of medium expansion on the thermalization problem
and estimate the average transverse momentum diffusivity for thermalization in
a Bjorken expanding medium.Comment: 8 pages, 4 figures. Current version includes updated references and a
more detailed discussion on the underlying assumption

Infantile myofibromatosis - a clinical and pathological diagnostic challenge
Infantile myofibromatosis is a rare disorder of fibroblastic/myofibroblastic proliferation and represents the most frequent type of mesenchymal tumor in the neonatal period and primary infancy.Three clinical types have been described: solitary, multicentric, and generalized (with visceral involvement). A correct characterization of the histopathology is essential to diagnose these neoplasias in early infancy. We present a case of multicentric infantile myofibromatosis with regression over time.info:eu-repo/semantics/publishedVersio
