34. Dynamical observables for a J=1/2 system within a fully Poincare'-covariant framework

Dr Giovanni Salme' (Istituto Nazionale di Fisica Nucleare -)

5/17/18, 2:00 PM

The formalism based on the Poincare' covariant spin-dependent spectral function, recently introduced [1] within the light-front (LF) Hamiltonian dynamics, allows one to develop a phenomenological tool for investigating three-fermion bound systems, in particular their dynamical observables. As it is well-known, several and quite relevant efforts are underway at JLAB with the aim of...

38. Basis Light-Front Quantization Approach to Proton

Dr Chandan Mondal (Institute of Modern Physics, Chinese Academy of Sciences)

5/17/18, 2:20 PM

Basis Light-front Quantization (BLFQ) has been proposed as a nonperturbative framework for solving quantum field theory. Based on the resulting light-front wave function obtained within the BLFQ framework, we investigate the several aspects of the nucleon properties such as electromagnetic form factors, generalized parton distributions (GPDs) etc.. In the effective Hamiltonian, we implement a...

18. Basics light front quantization for the light mesons

Dr Shaoyang Jia (Department of Physics and Astronomy, Iowa State University)

5/17/18, 2:40 PM

We propose an effective Hamiltonian for the valance Fock sectors of mesons to implement the chiral quark condensate based on the Nambu-Jona-Lasinio model. Such a term allows us to generalize the basis light front quantization framework with the longitudinal confinement ansatz and the one-gluon exchange potential to the pi and rho mesons. The multi-flavor version of the effective Hamiltonian is...

15. Radiative transitions between 0-+ and 1-- heavy quarkonia on the light front

Meijian Li (Iowa State University)

5/17/18, 3:00 PM

We present calculations of radiative transitions between vector and pseudoscalar quarkonia in the light-front Hamiltonian approach. The light-front wavefunctions of heavy quarkonia are obtained from the Basis Light-Front Quantization (BLFQ) approach in a holographic basis. We study the transition form factor with both the traditionally used ``good current'' $J^+=J^0+J^z$ and the...

41. Light-front Hadronic Models

sirajudheen Kuthini Kunhammed (The University of Iowa)

5/17/18, 3:20 PM

A class of Phenomenological models of hadronic systems motivated by QCD that have dual representations as a theory of quarks interacting with gluons and hadrons exchanging mesons are investigated. The model is formulated as a fully relativistic model with a light-front kinematic symmetry. The bare meson wave functions and production vertices are determined by the underlying QCD degrees of...
