Combined analysis of Z' -> t tbar and Z' -> t tbar j production for vector resonance searches at LHC

F. del Aguila, J. A. Aguilar-Saavedra, M. Moretti +3

We have implemented a code for Z' + n jets production in ALPGEN, with Z' decays into several final states, including l+ l- and t tbar. The MLM prescription is used for matching the…

At the borderline between exclusive and inclusive physics: Study of Drell-Yan fragments in the PANDA experiment (A preliminary simulation)

Andrea Bianconi

Here a preliminary study is presented concerning the detection of the normally unseen Drell-Yan fragments, possible in the PANDA experiment. To work as a multi-purpose apparatus, t…

Transverse momentum dependent parton distributions and azimuthal asymmetries in light-cone quark models

B. Pasquini, S. Boffi, A. V. Efremov +1

We review the information on the spin and orbital angular momentum structure of the nucleon encoded in the T-even transverse momentum dependent parton distributions within light-co…

Quest for precision in hadronic cross sections at low energy: Monte Carlo tools vs. experimental data

S. Actis, A. Arbuzov, G. Balossini +53

We present the achievements of the last years of the experimental and theoretical groups working on hadronic cross section measurements at the low energy e+e- colliders in Beijing,…

Azimuthal asymmetries in exclusive four-particle "Drell-Yan" events, with lepton-antilepton plus proton-antiproton detection, in proton-antiproton scattering

Andrea Bianconi

I study hard collisions between unpolarized protons and antiprotons where a lepton-antilepton pair is detected in coincidence with a final proton-antiproton pair, and no more parti…

Generalized parton distributions of the pion in a covariant Bethe-Salpeter model and light-front models

T. Frederico, E. Pace, B. Pasquini +1

The generalized parton distributions of the pion are studied within different light-front approaches for the quark-hadron and quark-photon vertices, exploring different kinematical…

Light-front interpretation of Proton Generalized Polarizabilities

M. Gorchtein, C. Lorcé, B. Pasquini +1

We extend the recently developed formalism to extract light-front quark charge densities from nucleon form factor data to the deformations of these quark charge densities when appl…

The spin structure of the nucleon in light-cone quark models

B. Pasquini, S. Boffi, P. Schweitzer

The quark spin densities related to generalized parton distributions in impact-parameter space and to transverse-momentum dependent parton distributions are reviewed within a light…

Probing the parton content of the nucleon

S. Boffi, B. Pasquini

The parton content of the nucleon is explored within a meson-cloud model developed to derive light-cone wave functions for the physical nucleon. The model is here applied to study…

Supersymmetric particle mass measurement with the boost-corrected contransverse mass

Giacomo Polesello, Daniel R. Tovey

A modification to the contransverse mass (MCT) technique for measuring the masses of pair-produced semi-invisibly decaying heavy particles is proposed in which MCT is corrected for…

From the LHC to Future Colliders

A. De Roeck, J. Ellis, C. Grojean +61

Discoveries at the LHC will soon set the physics agenda for future colliders. This report of a CERN Theory Institute includes the summaries of Working Groups that reviewed the phys…

Reply to "Comment on `The polarizability of the pion: no conflict between dispersion theory and chiral perturbation theory'"

B. Pasquini, D. Drechsel, S. Scherer

We reply to the Comment by Fil'kov and Kashevarov, arXiv:0805.4486 [hep-ph]. We show that the discrepancies between ChPT and dispersion theory, reported for the polarizability of t…

Pion Generalized Parton Distributions with covariant and Light-front constituent quark models

T. Frederico, E. Pace, B. Pasquini +1

We investigate the model dependence of no-helicity flip generalized parton distribution of the pion upon different approaches for the quark-hadron and quark-photon vertexes, in the…

Combination of electroweak and QCD corrections to single W production at the Fermilab Tevatron and the CERN LHC

G. Balossini, C. M. Carloni Calame, G. Montagna +5

Precision studies of the production of a high-transverse momentum lepton in association with missing energy at hadron colliders require that electroweak and QCD higher-order contri…

Is the X(3872) Production Cross Section at Tevatron Compatible with a Hadron Molecule Interpretation?

C Bignamini, B Grinstein, F Piccinini +2

The X(3872) is universally accepted to be an exotic hadron. In this letter we assume that the X(3872) is a D0 \bar D0* molecule, as claimed by many authors, and attempt an estimate…

Parton content of the nucleon from distribution amplitudes and transition distribution amplitudes

B. Pasquini, M. Pincetti, S. Boffi

The nucleon distribution amplitudes and the nucleon-to-pion transition distribution amplitudes are investigated at leading twist within the frame of a light-cone quark model. The d…
