Tests of the Standard Model in Neutron Beta Decay with Polarized Neutron
  and Electron and Unpolarized Proton
  We analyse the electron--energy and angular distribution of the neutron beta
decay with polarized neutron and electron and unpolarized proton, calculated in
Phys. Rev. C 95, 055502 (2017) within the Standard Model (SM), by taking into
account the contributions of interactions beyond the SM. After the absorption
of vector and axial vector contributions by the axial coupling constant and
Cabibbo-Kobayashi-Maskawa (CKM) matrix element (Bhattacharya et al., Phys. Rev.
D 85, 054512 (2012) and so on) these are the contributions of scalar and tensor
interactions only. The neutron lifetime, correlation coefficients and their
averaged values, and asymmetries of the neutron beta decay with polarized
neutron and electron are adapted to the analysis of experimental data on
searches of contributions of interactions beyond the SM. Using the obtained
results we propose some estimates of the values of the scalar and tensor
coupling constants of interactions beyond the SM. We use the estimate of the
Fierz interference term "b_F = - 0.0028 +/- 0.0026" by Hardy and Towner (Phys.
Rev. C 91, 025501 (2015)), the neutron lifetime "tau_n = 880.2(1.0)s"(Particle
Data Group, Chin. Phys. C 40, 100001 (2016)) and the experimental data
"N_{\exp} = 0.067 +/- 0.011_{\rm stat.} +/- 0.004_{\rm syst.}" for the averaged
value of the correlation coefficient of the neutron-electron spin-spin
correlations, measured by Kozela et al. (Phys. Ref. C 85, 045501 (2012)). The
contributions of G-odd correlations are calculated and found at the level of
10^{-5} in agreement with the results obtained by Gardner and Plaster (Phys.
Rev. C 87, 065504 (2013)).
