Momentum distributions in light halo nuclei and structure constraints

EPJ Web of Conferences, 2016
The core recoil momentum distribution of neutron-rich isotopes of light exotic nuclei is studied within a three-body model, where the nuclei are described by a core and two neutrons, with interactions dominated by the s-wave channel.

The Spectral Distribution of Firefly Light [PDF]

The Journal of General Physiology, 1964
The in vivo emission spectra of sixteen species of Jamaican fireflies and four species of American fireflies have been measured with a photoelectric recording spectrometer. A simple technique of stimulation with ethyl acetate vapor was found to elicit bright continuous emission over a period of several minutes.

In-medium pion valence distributions in a light-front model

Physics Letters B, 2017
Pion valence distributions in nuclear medium and vacuum are studied in a light-front constituent quark model. The in-medium input for studying the pion properties is calculated by the quark-meson coupling model.

New shapes of light-cone distributions of the transversely polarized \rho-mesons [PDF]

, 2000
We re-analyze the leading twist light-cone distributions for transversely polarized \rho-, \rho'- and b_1-mesons in the framework of QCD sum rules with nonlocal condensates.

Generelized Parton Distributions in light meson production

, 2011
We analyze light meson electroproduction within the handbag model, where the amplitude factorizes into Generelized Parton Distributions (GPDs) and a hard scattering part.

Generalized parton distributions and double distributions for q q-bar pions [PDF]

, 2002
We consider two simple covariant models for pions (one with scalar and the other with spin-1/2 constituents). Pion generalized parton distributions are derived by integration over the light-cone energy.

Basis light-front quantization approach to photon

Physics Letters B, 2022
We solve for the light-front wave functions (LFWFs) of the physical photon from the eigenvectors of the light-front quantum electrodynamics (QED) Hamiltonian with the aim to determine its bare photon and electron-positron Fock components.

The radial distributions of a heavy-light meson on a lattice [PDF]

, 2002
In an earlier work, the charge (vector) and matter (scalar) radial distributions of heavy-light mesons were measured in the quenched approximation on a 16^3 times 24 lattice with a quark-gluon coupling of 5.7, a lattice spacing of 0.17 fm, and a hopping ...
