  1. 125. Inclusive three- and four-jet production in multi-Regge kinematics at the LHC
    Francesco Giovanni Celiberto (CS)

    Progress in QCD
    In this talk a study of differential cross sections for the production of three and four jets in multi-Regge kinematics is presented. The main focus lies on the azimuthal angle dependences in events with two forward/backward jets tagged in the final state. Furthermore, the tagging of one or two extra jets in more central regions of the detector with a relative separation in rapidity from each...

  2. 121. Computation of NLO processes involving heavy quarks using Loop-Tree Duality

    Progress in QCD
    We present a new method to compute higher-order corrections to physical cross-sections, at Next-to-Leading Order and beyond. This method, based on the Loop Tree Duality, leads to locally integrable expressions in four dimensions. By introducing a physically motivated momentum mapping between the momenta involved in the real and the virtual contributions, infrared singularities naturally...

  3. 131. What can we learn from dilepton angular distributions at Z0 peak at the LHC?

    Progress in QCD
    Recently ATLAS published new data on dilepton angular coefficients in Z-boson production at the energy 8 TeV. In particular the famous Lam-Tung relation was shown to be broken and NNLO QCD corrections could explain only a fraction of this phenomenon. We investigate properties of the dilepton angular distributions and Lam-Tung relation breaking within kT-factorization framework and confront...

  4. 96. Estimating the branching fraction for $B^0\rightarrow \psi(2S)\pi^0$ decay
    Behnam Mohammadi (Urmia University)

    Progress in QCD
    I present estimates of the branching fractions in the non-leptonic charmonium two-body decay rates for $B^0\rightarrow \psi(2S)\pi^0$ decay and the same decays of $B^+\rightarrow \psi(2S)\pi^+$, $B^0\rightarrow \psi(2S)K^0$ and $B^+\rightarrow \psi(2S)K^+$. These estimates are based on a generalized factorization approach making use of leading order (LO) and next-to-leading order...

  5. 168. Small-x resummation for DVCS, TCS and exclusive vector meson production
    Dmitry Ivanov (Sobolev Institute of Mathematics)
    07/09/2016, 10:40
    Progress in QCD
    Some hard exclusive processes can be described in a framework of QCD collinear factorization. The amplitudes of Deeply Virtual Compton Scattering (DVCS), its crossing counterpart Timelike Compton Scattering (TCS) and the amplitudes of neutral light and heavy vector meson (VM) production can be calculated as a convolution of hard coefficient functions and generalized parton distributions. ...
