Beam-normal single-spin asymmetry in elastic scattering of electrons from a spin-0 nucleus
Oleksandr Koshchii, Mikhail Gorchtein, Xavier Roca-Maza +1
We study the beam-normal single-spin asymmetry (BNSSA) in high-energy elastic electron scattering from several spin-0 nuclei. Existing theoretical approaches work in the plane-wave…
Weak charge and weak radius of C
Oleksandr Koshchii, Jens Erler, Mikhail Gorchtein +5
We present a feasibility study of a simultaneous sub-percent extraction of the weak charge and the weak radius of the C nucleus using parity-violating electron scattering,…
Reduced uncertainty of the axial -box correction to the proton's weak charge
Jens Erler, Mikhail Gorchtein, Oleksandr Koshchii +2
We present the fully up-to-date calculation of the -box correction which needs to be taken into account to determine the weak mixing angle at low energies from parity-violating…
Lepton mass effects for beam-normal single-spin asymmetry in elastic muon-proton scattering
Oleksandr Koshchii, Andrei Afanasev
We estimate the beam-normal single-spin asymmetry in elastic lepton-proton scattering without employing the ultrarelativistic approximation. Our calculation is relevant for analyse…
Charge and spin asymmetries in elastic lepton-nucleon scattering
Oleksandr Koshchii, Andrei Afanasev
Elastic lepton scattering off of a nucleon has proved to be an efficient tool to study the structure of the hadron. Modern cross section and asymmetry measurements at Jefferson Lab…
Target-normal single-spin asymmetry in elastic electron-nucleon scattering
Oleksandr Koshchii, Andrei Afanasev
We estimate the target-normal single-spin asymmetry at nearly forward angles in elastic electron-nucleon scattering. In the leading-order approximation, this asymmetry is proportio…
Two-particle photodisintegration of He-4: He-4(gamma,d)d, He-4(gamma,p)T, He-4(gamma,n)He-3
O. E. Koshchii, P. E. Kuznietsov, Yu. A. Kasatkin
Using a covariant diagram technique and the concept of a nucleus as an elementary particle we calculated differential cross-sections for two-particle photodisintegration reactions…
