Attraction between quarks is a fundamental aspect of QCD. It is plausible that several of the most profound aspects of low-energy QCD dynamics are connected to diquark correlations, including: paucity of exotics (which is the foundation of the quark model and of traditional nuclear physics), similarity of mesons and baryons, color superconductivity at high density, hyperfine splittings, ∆I = 1/...

We compute dijet production in Deep Inelastic Scattering at low $x$ the dipole formalism next-to-eikonal accuracy. calculate contributions induced by single photon exchange of either longitudinal or transverse polarization. include all types corrections to eikonal approximation gluon background field: (i) finite width target, (ii) interaction quark-antiquark pair with subleading (transverse) co...

We propose the boost asymmetry of diboson productions in pp collisions as a new experimental observable, which can provide unique information on proton structure. The rises difference kinematics two bosons, that are coupled to different quark and antiquark initial states, respectively, thus reflects features parton densities. By comparing such boson energy or rapidity, events with having higher...
