We show that when saturation effects are included one obtains a good description of the exclusive $\mathrm{J}/\ensuremath{\psi}$ production spectra in ultraperipheral lead-lead collisions as recently measured by ALICE Collaboration at LHC. As sensitive to spatial distribution nuclear matter small Bjorken-$x$, this implies gluon modify impact parameter profile target we move towards $x$. In addi...

We apply a novel factorization formula recently developed within NRQCD framework to analyze the exclusive production of fully-charmed tetraquark T4c plus hard photon at super B factory. For simplicity, in this work we have concentrated on 0++ and 2++ associated with photon. With some rough estimates about unknown nonperturbative matrix elements simplified diquark-antidiquark model, predict rate...

We present results on the Central Exclusive Production of charged particle pairs h^{+}h^{-} h+h− ( h = \pi, K, p display="inline">h=<mml:...
