Description

An international Conference "Hadron Structure and QCD" (HSQCD'2016) is organized by Petersburg Nuclear Physics Institute of National Research Centre "Kurchatov Institute", St. Petersburg State University, St. Petersburg Polytechnic University, V.A. Fock Institute of Physics, Institute of Physics of Slovak Academy of Sciences and Comenius University, Bratislava. It will be held on June 27 - July 1, 2016 at Gatchina, a picturesque southern suburb of St. Petersburg, especially wonderful in period of the famous white nights. Plenary and parallel sessions will be carried out at the site of Petersburg Nuclear Physics Institute NRC KI, Gatchina. The aim of this Conferences is to review the recent progress in the hadronic physics, QCD, the Standard Model and its generalizations.

The joint Conference unifies the series of two Conferences: "Hadron Structure" held in Slovakia from 1973, and "Hadron Structure and QCD" held in St. Petersburg from 2004. Now the joint Conference is carried out annually, in the odd years in Slovakia and in the even years in Russia. The first joint Conference HS’07 was held in Slovakia, 2007.

The physics topics of the Conference include:

  • perturbative QCD, DGLAP- and BFKL-evolutions
  • polarized and nonpolarized parton distribution functions
  • Pomeron, hard diffraction and small-x physics
  • heavy-ion collisions, quark-gluon matter
  • nonperturbative QCD, lattice computations, chiral model of hadrons
  • hadron spectroscopy, exotic states
  • physics of the LHC and future colliders
  • precision tests of the Standard Model, extensions of the Standard Model
  • neutrino physics

        Towards NLO computations in the Parton Reggeization Approach 20m

        The Parton Reggeization Approach (PRA) is the hybrid scheme of kT-factorization which combines the gauge-inveriant definition of hard-scattering matrix elements with Reggeized (off-shell) initial state partons, derived using L. N. Lipatov's effective theory for the Regge limit of QCD, and the Kimber-Martin-Ryskin scheme for the determination of unintegrated PDFs. The LO PRA description of multiscale observables, sensitive to the multiple hard emissions (dijet azimutal decorrelations, pT-spectra, polarization observables in Drell-Yan) was rather successful. However, the full NLO calculations are required to describe the observables, sensitive to soft emissions and to test the stability of the description w. r. t. NLO corrections.

        The issues of double-counting subtraction for the real NLO corrections, and rapidity divergences for virtual NLO corrections will be described in the talk. The different regularization schemes for rapidity divergences will be discussed. The application of the covariant regularization scheme by [A. S. Vera, M. Hentschinski, 2012] to the case of Reggeized quarks will be presented.

        Puzzling production of heavy flavored hadrons 30m

        The masses of cryptoexotic pentaquarks with hidden beauty are estimated phenomenologically using the results by the LHCb collaboration which discovered recently the cryptoexotic pentaquarks with hidden charm [1]. The expected masses of the hidden beauty pentaquarks are about 10.8 GeV and 10.7 GeV in the limit of some kind of heavy quark symmetry [2]. The states with hidden strangeness considered in similar way have masses about 2.37 Gev and 2.30 GeV, by several hundreds of MeV higher than states discussed previously in connection with the relatively light positive strangeness pentaquark θ + [3, 4]. Empirical data on spectra of pentaquarks can be used to get information about quarkonia interaction with nucleons. The results obtained for the case of heavy flavors are in fair agreement with model of isospin (pion) exchange between flavored baryons and anti-flavored vector mesons, proposed by Karliner and Rosner, and in qualitative agreement with the bound state version of the chiral soliton model. The influence of the change of soliton dimension (squeezing) on the energy of quantized states is investigated.

        Legendre analysis of hadronic reactions 20m

        Modern experimental facilities and detectors provide tremendous volume of detailed data. For double-hadron reactions, they are usually presented as a set of many panels for, e.g., angular distributions at many particular energies. Such presentation loses visuality, and its physical content may be extracted only through some model-dependent treatment. Instead, we suggest to use expansion into the Legendre series with a relatively small number of essential coefficients. This approach was applied in several experimental investigations and demonstrated its higher visualization. The talk presents some general properties of the Legendre coefficients which allow to extract physical information even without any model-dependent assumptions.

        High precision data on pion-proton elastic cross-section 30m

        EPECUR experiment finished processing of pion-nucleon data recorded before the fire at the ITEP proton syncrotron in 2011. More than 9000 cross section data points with extraordinary accuracy of 1% are presented both for positive and negative pion scattering on protons in the energy range 820-1330 MeV/c. The data are arranged in 2 degree angular intervals with approximately 5 MeV/c energy step.

        Negative pion-proton results reveal hints to a narrow resonance-like structure near 1680 MeV. Possible explanations of such effect are discussed in the talk.

        A search for narrow structures was also performed in inclusive inelastic data with one or two charged tracks in the acceptance of the setup. Yet no effect of any significance is observed.

        Today EPECUR nearly finished preparations for the second stage of the experiment and is considering several possibilities for continuation of the experiment with medium energy pion beams.

        Mass spectra of singly bottom baryon Omega_b^- using the Hypercentral Constituent Quark Model 20m

        The mass spectra of singly bottom baryon Ω−b is determined using the Hypercentral Constituent Quark Model [1]. We first determine ground state masses and then established the radial(L=0) and orbital (L=1,2,3) excited state masses. The confinement potential is assumed in the hyper central co-ordinates of the coulomb plus power potential for un- equal masses. We also introduced first order correction to the potential. Ω − b with quark content ssb has SU(3) 6 F symmetry. Our calculated mass spectra for Ω − b is obtained by varying potential index ν value from 0.5 to 2.0. Only ground state is found till now experimentally [2] m Ω − = 6048.8 ± 3.2 MeV with J P = b 1 + . 2 + Recent Lattice QCD re- sults [3] are m Ω − (1/2) + =6056(47)(20) MeV and m Ω − (3/2) =6085(47)(20) are close to b b our results m Ω − (1/2) + =6048 MeV and m Ω − (3/2) + =6086 MeV at potential index ν =1.0. b b Radially excited states are calculate for J P = calculated for 5 + 7 + 1 − 3 − 5 − 7 − 9 − , 2 , 2 , 2 , 2 , 2 , 2 2 1 + 1 + 3 + , 2 , 2 2 and orbitally excited states are at ν=1.0. We also plot Regge trajectory(M 2 → n) for higher excited states. We also compare our results with other theoretical models [4, 5, 6] and they are in good agreement.
