Transverse-momentum-dependent parton distributions (TMDs)

Alessandro Bacchetta

Transverse-momentum-dependent parton distributions (TMDs) provide three-dimensional images of the partonic structure of the nucleon in momentum space. We made impressive progress i…

Light-front transverse charge densities

Cédric Lorcé, Barbara Pasquini, Marc Vanderhaeghen

We discuss the recent interpretation of quark-distribution functions in the plane transverse to the light-cone direction. Such a mapping is model independent and allows one to buil…

Dihadron fragmentation functions and their relevance for transverse spin studies

A. Courtoy, A. Bacchetta, M. Radici

Dihadron fragmentation functions describe the probability that a quark fragments into two hadrons plus other undetected hadrons. In particular, the so-called interference fragmenta…

The 2^-+ assignment for the X(3872)

T. J. Burns, F. Piccinini, A. D. Polosa +1

Very recently the BaBar collaboration has put forward a claim that the X(3872) is not a 1^++ resonance, as most of the phenomenological work on the subject was relying on, but rath…

Light-Front Densities for Transversely Polarized Hadrons

C. Lorcé, B. Pasquini, M. Vanderhaeghen

We discuss the recent interpretation of quark distribution functions in the plane transverse to the light-cone direction. Such a mapping is model independent and allows one to buil…

Modeling the transverse momentum dependent parton distributions

B. Pasquini, C. Lorce'

We review quark model calculations of the transverse momentum dependent parton distributions (TMDs). For the T-even TMDs, we discuss the physical origin of model relations which ho…

Production of Light Higgs Pairs in 2-Higgs Doublet Models via the Higgs-strahlung Process at the LHC

M. Moretti, S. Moretti, F. Piccinini +2

At the Large Hadron Collider, we prove the feasibility to detect pair production of the lightest CP-even Higgs boson h of a Type II 2-Higgs Doublet Model through the process q \bar…

Radiative Events as a Probe of Dark Forces at GeV-Scale e+ e- Colliders

L. Barze', G. Balossini, C. Bignamini +4

High-luminosity e+ e- colliders at the GeV scale (flavor factories) have been recently recognized to be an ideal environment to search for a light weakly coupled vector boson U (da…

Weighted azimuthal asymmetries in a diquark spectator model

Alessandro Bacchetta, Marco Radici, Francesco Conti +1

We analytically calculate weighted azimuthal asymmetries in semi-inclusive lepton-nucleon deep-inelastic scattering and Drell-Yan processes, using transverse-momentum-dependent par…

Higher order forward spin polarizability

B. Pasquini, P. Pedroni, D. Drechsel

As a guideline for future experiments to extract the four (leading) spin polarizabilities of the nucleon, we have constructed the forward amplitude for polarized Compton scattering…

Status and accuracy of the Monte Carlo generators for luminosity measurements

G Montagna, G Balossini, C Bignamini +3

The status and accuracy of the precision Monte Carlo generators used for luminosity measurements at flavour factories is reviewed. It is shown that, thanks to a considerable, long-…

Longitudinal and Transverse Parton Momentum Distributions for Hadrons within Relativistic Constituent Quark Models

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

Longitudinal and transverse parton distributions for pion and nucleon are calculated from hadron vertexes obtained by a study of form factors within relativistic quark models. The…

Strong Double Higgs Production at the LHC

Roberto Contino, Christophe Grojean, Mauro Moretti +2

The hierarchy problem and the electroweak data, together, provide a plausible motivation for considering a light Higgs emerging as a pseudo-Goldstone boson from a strongly-coupled…

More loosely bound hadron molecules at CDF?

C Bignamini, B Grinstein, F Piccinini +3

In a recent paper we have proposed a method to estimate the prompt production cross section of X(3872) at the Tevatron assuming that this particle is a loosely bound molecule of a…

Phases of Augmented Hadronic Light-Front Wave Functions

Stanley J. Brodsky, Barbara Pasquini, Bowen Xiao +1

It is an important question whether the final/initial state gluonic interactions which lead to naive-time-reversal-odd single-spin asymmetries and diffraction at leading twist can…

Sivers and Boer-Mulders functions in Light-Cone Quark Models

B. Pasquini, F. Yuan

Results for the naive-time-reversal-odd quark distributions in a light-cone quark model are presented. The final-state interaction effects are generated via single-gluon exchange m…

A method for tuning parameters of Monte Carlo generators and a its application to the determination of the unintegrated gluon density

Alessandro Bacchetta, Hannes Jung, Albert Knutsson +2

A method for tuning parameters in Monte Carlo generators is described and applied to a specific case. The method works in the following way: each observable is generated several ti…
