Proton structure, Partons, QCD, DGLAP and beyond
We present an introductory discussion of deep-inelastic lepton-proton scattering as a means to probe the substructure of the proton. A résumé of QCD is given, emphasizing the running of the coupling constant and the DGLAP evolution equations for the parton densities. The determination of parton distributions is discussed and their importance for predictions of processes at the LHC is emphasized...
متن کاملKaons and pions in strange quark matter
The behavior of kaons and pions in strange quark matter in weak equilibrium, is investigated within the SU(3) Nambu-Jona-Lasinio [NJL] model. This work focuses a region of high densities where the behavior of mesons has not been explored in the framework of this model. It is found that above the density where strange valence quarks appear in the medium, ρ = 3.8ρ0, a change of behavior of differ...
متن کاملGoldstone Boson's Valence-quark Distribution *
Dynamical chiral symmetry breaking (DCSB) is one of the keystones of low-energy hadronic phenomena. Dyson-Schwinger equations provide a model-independent quark-level understanding and correlate that with the behaviour of the pion’s Bethe-Salpeter amplitude. This amplitude is a core element in the calculation of pion observables and combined with the dressed-quark Schwinger function required by ...
متن کاملSmall-Q extension of DGLAP-constrained Regge residues
In a previous paper, we have shown that it was possible to use the DGLAP evolution equation to constrain the high-Q (Q ≥ 10 GeV) behaviour of the residues of a high-energy Regge model, and we applied the developed method to the triple-pole pomeron model. We show here that one can obtain a description of the low-Q γp data matching the high-Q results at Q = 10 GeV. We know that one can use Regge ...
متن کاملTop quark associated production of topcolor pions at hadron colliders
We investigate the associated production of a neutral physical pion with top quarks in the context of topcolor assisted technicolor. We find that single-top associated production does not yield viable rates at either the Tevatron or LHC. tt̄-associated production at the Tevatron is suppressed relative to Standard Model tt̄H, but at the LHC is strongly enhanced and would allow for easy observation...
