Asymptotics of density distributions, momentum distributions and form factors of three-nucleon nuclei [PDF]

open access: yesЯдерна фізика та енергетика, 2010
The structure functions of three-nucleon nuclei 3H and 3He are investigated, and asymptotics of density distributions of nucleons at large distances are established using bound state wave functions with high precision.

FORM FACTORS OF PION AND KAON [PDF]

open access: yesInternational Journal of Modern Physics A, 2000
The form factors of pion and kaon are studied by an effective chiral theory of large NC QCD. Besides the vector meson poles an additional intrinsic form factors are found. Theory agrees well with data in both time-like and space-like regions. There is no adjustable parameter.

A Vertex Operator Approach for Form Factors of Belavin's (Z/nZ)-Symmetric Model and Its Application

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
A vertex operator approach for form factors of Belavin's (Z/nZ)-symmetric model is constructed on the basis of bosonization of vertex operators in the A_{n−1}^{(1)} model and vertex-face transformation.

Baryon form factors

open access: yes
We review the status of baryon form factors with a special focus on the nucleon electromagnetic form factors which are known best. First, we give an introduction into the dispersive analyses and emphasize the role of unitarity and analyticity in the construction of the isoscalar and isovector spectral functions.

Meson electromagnetic form factors

open access: yesEPJ Web of Conferences, 2012
The electromagnetic structure of the pseudoscalar meson nonet is completely described by the sophisticated Unitary&Analytic model, respecting all known theoretical properties of the corresponding form factors.

Parametrization of transition energy-momentum tensor form factors

open access: yesPhysics Letters B, 2022
While the Lorentz structures of the N→Δ transition matrix element of the vector current are well-known, that of the symmetric energy-momentum tensor current is unknown.

Finite-Temperature Form Factors: a Review

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
We review the concept of finite-temperature form factor that was introduced recently by the author in the context of the Majorana theory. Finite-temperature form factors can be used to obtain spectral decompositions of finite-temperature correlation ...
