75. Inclusive dihadron production at the LHC in the NLA BFKL

Francesco Giovanni Celiberto (Università della Calabria and INFN Cosenza (Italy))

Forward physics (Low-x QCD)

The inclusive production of a pair of hadrons (a “di-hadron” system), having high transverse momenta and separated by a large interval of rapidity, is investigated. This process has much in common with the widely discussed Mueller-Navelet jet production and can be also used to access the BFKL dynamics at proton colliders. The first full NLA BFKL analysis for cross sections and azimuthal angle...

23. Photoproduction of J/Psi with dissociation of protons

Wolfgang Schaefer (Institute of Nuclear Physics PAN)

Forward physics (Low-x QCD)

We present the cross sections for both electromagnetic and diffractive dissociation of protons for semiexclusive production of J/ψ mesons in proton-proton collisions at the LHC.

Differential distributions in missing mass (MX), or single-particle variables related exclusively to the J/ψ meson are calculated for s√ = 7 TeV and 13 TeV.. We compare the distributions for purely electromagnetic...

66. Higher-twist corrections to gluon TMD factorization

Forward physics (Low-x QCD)

I discuss the power corrections to TMD factorization for particle production
by gluon-gluon fusion in hadron-hadron collisions

29. Triple-parton scattering effects in D meson production at the LHC

Antoni Szczurek (Institute of Nuclear Physics)

Forward physics (Low-x QCD)

We investigate whether the triple-parton scattering effects can be observed in open charm production in proton-proton collisions at the LHC.
We use so-called factorized Ansatz for calculations of hard multiple-parton interactions. The numerical results for each parton interaction are obtained within the $k_{T}$-factorization approach. Predictions for one, two and three $c\bar c$ pairs...

53. The tensor pomeron and low x DIS

Otto Nachtmann (U), Rainer Schicker (Ruprecht-Karls-Universitaet Heidelberg (DE))

Forward physics (Low-x QCD)

The tensor-pomeron model is applied to low x deep-inelastic lepton-nucleon
scattering (DIS). In addition to the soft tensor pomeron, which has proven
quite successful for the description of soft hadronic high-energy reactions,
we consider a hard tensor pomeron. The combination of these two pomeron
exchanges and the f2 reggeon exchange allows a description of the absorption
cross sections of...

42. Inclusive production of vector quarkonia at the LHC

Anna Cisek (University of Rzeszow)

29/06/2017, 14:37

Forward physics (Low-x QCD)

We discuse prompt production of $J/\psi$ mesons in proton-proton collisions at the LHC within NRQCD $k_{t}$ factorization approach using Kimber-Martin-Ryskin (KMR) and Kutak-Stasto (KS) unintegrated gluon distribution (UGDF). We include both direct color-singlet production ($gg \to J/\psi g$) as well as a feed-down from $\chi_{c} \to J/\psi \gamma$ and $ \psi' \to J/\psi X$. The corresponding...

67. Effects of parton shower dynamics on PDF evolution

Radek Zlebcik (Deutsches Elektronen-Synchrotron (DE))

29/06/2017, 14:59

Forward physics (Low-x QCD)

We present results from a parton branching solution of the DGLAP equation which includes the transverse momentum distributions for all parton flavours.
The resulting parton distributions are confronted with semi-analytical DGLAP solution as well as with distributions obtained by Pythia parton-shower machinery.
In this way we test the consistency between Monte Carlo parton-showers and the PDFs...

37. Associated production of D mesons with one and two jets at the LHC

Rafal Maciula (Institute of Nuclear Physics PAN)

29/06/2017, 15:21

Forward physics (Low-x QCD)

We have studied production of open charm mesons in association with one or two jets at the LHC.
The cross sections for $c\bar{c}+\mathrm{jet}$ and $c\bar{c}+\mathrm{2jets}$ final states production
are calculated in the leading-order collinear approximation as well as in the $k_{T}$-factorization
approach, where a part of higher order corrections is effectively included.

Both processes under...
