چکیده
We investigate the twist-3 transverse-momentum-dependent parton distribution functions (TMDs) of pion with basis light-front quantization. The TMDs are not independent and can be decomposed into twist-2 genuine terms from equations motion (EOM). compute resulting wave obtained by diagonalizing QCD Hamiltonian, determined for pion's constituent quark-antiquark quark-antiquark-gluon Fock sectors, three-dimensional confinement. also obtain (PDFs) show that they preserve sum rule, which affirms robustness our approach. This is first time theoretical predictions made subleading twist structures containing interference between two sectors.

Transverse pion structure beyond leading twist in constituent models
The understanding of the pion structure as described in terms of transverse-momentum-dependent parton distribution functions (TMDs) is of importance for the interpretation of currently ongoing Drell-Yan experiments with pion beams. In this work we discuss the description of pion TMDs beyond leading twist in a pion model formulated in the light-front constituent framework. For comparison, we als...
متن کاملElectron Anomalous Magnetic Moment in Basis Light-Front Quantization Approach
We apply the Basis Light-Front Quantization (BLFQ) approach to the Hamiltonian field theory of Quantum Electrodynamics (QED) in free space. We solve for the mass eigenstates corresponding to an electron interacting with a single photon in light-front gauge. Based on the resulting non-perturbative ground state light-front amplitude we evaluate the electron anomalous magnetic moment. The numerica...
متن کاملLight Front Quantization
An introductory overview on Light-Front quantization, with some emphasis on recent achievements, is given. Light-Front quantization is the most promising and physical tool to study deep inelastic scattering on the basis of quark gluon degrees of freedom. The simplified vacuum structure (nontrivial vacuum effects can only appear in zero-mode degrees of freedom) and the physical basis allows for ...
متن کاملGlue in the light-front pion
It may be possible to approximate the full pion wave function in light-front QCD using only qq and qqg Fock space components. Removing zero modes and using invariant-mass cutoffs that make a constituent approximation possible leads to non-canonical terms in the QCD hamiltonian, and forces us to work in the broken symmetry phase of QCD in which chiral symmetry breaking operators must appear dire...
متن کاملLight - Front Quantization of Gauge Theories ∗
Light-front wavefunctions provide a frame-independent representation of hadrons in terms of their physical quark and gluon degrees of freedom. The light-front Hamiltonian formalism provides new nonperturbative methods for obtaining the QCD spectrum and eigensolutions, including resolvant methods, variational techniques, and discretized light-front quantization. A new method for quantizing gauge...
