The inclusive production of a ϒJ/ψ pair in proton-proton interactions at the LHCb is considered. This process is forbidden at the leading order of perturbation theory, so channels such as double parton scattering, χbχc pair production with subsequent radiative decays of P-wave quarkonia, contributions of color-octet states, and next-to-leading-order corrections are studied in detail. For all these channels we present theoretical predictions of the total cross sections at the LHCb and…

Production of heavy quarkonia in hadronic experiments
Processes of single and pair production of heavy quarkonia under LHC conditions have been studied within nonrelativistic quantum chromodynamics. Constraints on the matrix elements of color-singlet
Open charm production in double parton scattering processes in the forward kinematics
We calculate the rate of double open charm production in the forward kinematics studied recently in the LHCb experiment. We find that the mean field approximation for the double parton GPD
Complete Study of Hadroproduction of a ϒ Meson Associated with a Prompt J/ψ.
It is found that the effective cross section characterizing the importance of double-parton scatterings is σ_{eff}≤8.2  mb at 68% confidence level from the D0 measurement.
Production of χc pairs with large rapidity separation in kT factorization
We calculate the production of pairs of $\chi_c(J)$ mesons with all possible combinations of $J=0,1,2$. The leading order production mechanism is the crossed-channel gluon exchange in the gluon-gluon
Revealing minijet dynamics via centrality dependence of double parton interactions in proton–nucleus collisions
One of the main challenges hampering an accurate measurement of the double parton scattering (DPS) cross sections is the difficulty in separating the DPS from the leading twist (LT) contributions. We
RMS and charge radii in a potential model
The Dalgarno’s method of perturbation is used to solve the Schrodinger’s equation with the Cornell potential $$V(r)=-\frac{4\alpha _s}{3r}+br+c$$V(r)=-4αs3r+br+c. The short range and long range


The LHCb Collaboration
We measure the B0 − B0 mixing frequency ∆md using ∼ 6000 B0 → D−(K+π−π−)π+ candidates from 36 pb−1 of data taken in physics runs of the LHCb experiment in 2010. We use opposite and same side tagging
