Nuclear effects in photoproduction of heavy quarks and vector mesons in ultraperipheral PbPb and pPb collisions at the LHC
The comparison of photoproduction cross sections for and b-b(bar)
in PbPb and pPb collisions can give sensitivity to nuclear shadowing effects.
The photoproduction of vector mesons is even more sensitive to the underlying
gluon distributions. In this study we present the cross sections and rapidity
dependence of the photoproduction of heavy quarks and exclusive production of
vector mesons in ultraperipheral pPb and PbPb collisions at the Large Hadron
Collider at sqrt(s_NN)=5 TeV and sqrt(s_NN)=2.76J/\psi\Upsilon$ in
PbPb collisions in particular exhibit very good sensitivity to gluon shadowing.Comment: 4 pages, 4 figure
Constraining Gluon Shadowing Using Photoproduction in Ultraperipheral pA and AA Collisions
Photoproduction of heavy quarks and exclusive production of vector mesons in
ultraperipheral proton-nucleus and nucleus-nucleus collisions depend
significantly on nuclear gluon distributions. In the present study we
investigate quantitatively the extent of the applicability of these processes
at the Large Hadron Collider (LHC) in constraining the shadowing component of
nuclear gluon modifications.Comment: 15 pages, 10 figures. arXiv admin note: substantial text overlap with

Compensation in undoped and halogen doped CdTe crystals
A theoretical model is proposed which allows the calculation of the concentration of defects in pure and halogen compensated cadmium telluride grown by the THM method. All associations and ionization reactions are described in terms of the law of mass action. The ionization energies of the defects are taken from the energy level diagram established by taking into account the latest experimental data. The concentrations of the different defects calculated for chlorine doped material are in good agreement with that measured using a time of flight method
