“…We explicitly evolve our initial PDFs from the LCQM model for the pion to the relevant experimental scales μ 2 ¼ 16 GeV 2 using the Higher Order Perturbative Parton Evolution toolkit to numerically solve the NNLO DGLAP equations [150]. While applying the DGLAP equations numerically, we impose the condition that the running coupling α s ðμ 2 Þ saturates in the infrared at a cutoff value of max α s ¼ 1 [151][152][153][154].…”

We investigate the tomographical structure of the pion and kaon in the light-cone quark model. In particular, we study the parton distribution amplitude (PDA) of the pion and kaon. We obtain the parton distribution function (PDF) and the generalized parton distributions of the pion and kaon. The valence quark PDA and PDF of the pion, after QCD evolution, are found to be consistent with the data from the E791 and the E615 experiments at Fermilab, respectively. Further, we investigate the transverse momentum distributions (TMDs) of the pion and kaon. We also discuss the unpolarized TMD evolution for the pion and kaon in this model.

“…BLFQ has the advantage of being able to solve bound state problems involving positronium [37] and hadron structures [38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53]. In this paper we follow previous work on the physical electron eigenstates in BLFQ [54].…”

The framework of "time-dependent basis light-front quantization" (tBLFQ) offers a nonperturbative approach to scattering problems in external fields, based on Fock space truncation. Here we extend tBLFQ to include spatio-temporal field inhomogeneities in multiple spacetime directions. This extension is necessary for the proper modeling of e.g. intense laser fields. We focus on the example of nonlinear Compton scattering of an electron on an axicon-type laser, with an emphasis on the transverse structure of the beam. We analyze the impact of field intensity and particle energy, as well as basis truncation effects, on the radiation spectrum of the scattered electron.

We study all-charm tetraquarks in the Front Form of Hamiltonian dynamics using many-body basis function approach known as Basis Light Front Quantization. The model Hamiltonian contains transverse and longitudinal confining potentials and one-gluon-exchange effective potential. Apart from the tetraquark ground state mass we calculate also two-body and four-body estimates of meson-meson breakup threshold. The results suggest an unbound all-charm tetraquark. We discuss implications of the cluster decomposition principle for theories formulated on the Light Front and present our treatment of identical particles together with color-singlet restriction on the space of quantum states.
