Four-Quark Hadrons: an Updated Review

Angelo Esposito, Andrea L. Guerrieri, Fulvio Piccinini +2

The past decade witnessed a remarkable proliferation of exotic charmonium-like resonances discovered at accelerators. In particular, the recently observed charged states are clearl…

Angular momentum decomposition from a QED example

Tianbo Liu, Bo-Qiang Ma

We investigate the angular momentum decomposition with a quantum electrodynamics example to clarify the proton spin decomposition debates. We adopt the light-front formalism where…

Transverse-momentum dependent parton distribution functions beyond leading twist in quark models

C. Lorcé, B. Pasquini, P. Schweitzer

Higher-twist transverse momentum dependent parton distribution functions (TMDs) are a valuable probe of the quark-gluon dynamics in the nucleon, and play a vital role for the expla…

Dihadron Fragmentation Functions and Transversity

Marco Radici, A. Courtoy, Alessandro Bacchetta

We present preliminary results for an updated extraction of the transversity parton distribution based on the analysis of pion-pair production in deep-inelastic scattering off tran…

Production of two hadrons in semi-inclusive Deep Inelatic Scattering

Stephen Gliske, Alessandro Bacchetta, Marco Radici

We present the general expression, in terms of structure functions, of the cross section for the production of two hadrons in semi-inclusive deep-inelastic scattering. We analyze t…

W gamma production in hadronic collisions using the POWHEG+MiNLO method

Luca Barze, Mauro Chiesa, Guido Montagna +4

We detail a calculation of W gamma production in hadronic collision, at Next-to-Leading Order (NLO) QCD interfaced to a shower generator according to the POWHEG prescription supple…

Dispersive evaluation of the D-term form factor in deeply virtual Compton scattering

B. Pasquini, M. V. Polyakov, M. Vanderhaeghen

We present a dispersive representation of the D-term form factor for hard exclusive reactions, using unsubtracted -channel dispersion relations. The -channel unitarity relati…

Pion TMDs in light-front constituent approach, and Boer-Mulders effect in the pion-induced Drell-Yan process

B. Pasquini, P. Schweitzer

At leading twist the transverse-momentum dependent parton distributions of the pion consist of two functions, the unpolarized and the Boer-M…

Production of Tetraquarks at the LHC

A. L. Guerrieri, F. Piccinini, A. Pilloni +1

The high prompt production cross section of X(3872) at hadron colliders has shown to be very informative about the quark nature of the X, Y, Z states. We present here a number of r…

The Z(4430) and a New Paradigm for Spin Interactions in Tetraquarks

L. Maiani, F. Piccinini, A. D. Polosa +1

Following the recent confirmation of the Z+(4430) resonance with J^{PG}=1^{++}, we have re-examined the model of S- and P-wave tetraquarks. We propose a `type-II' diquark-antidiqua…

Twist-2 Generalized TMDs and the Spin/Orbital Structure of the Nucleon

K. Kanazawa, C. Lorcé, A. Metz +2

Generalized transverse-momentum dependent parton distributions (GTMDs) encode the most general parton structure of hadrons. Here we focus on two twist-2 GTMDs which are denoted by…
