The precision of correlation measurements in neutron and nuclear β decay has now
reached the level of about 1% and better. At this level of precision, higher-order corrections …

We investigate the reliability of the conservation of the vector current (CVC) hypothesis in the
neutron beta decay (n β− decay). We calculate the contribution of the phenomenological …

To continue from our previous work [Phys. Rev. D 109, 073007 (2024) PRVDAQ 2470-0010
10.1103/PhysRevD. 109.073007], we derive the full Standard Model prediction of the most …

A bstract We report a serious kinematics problem in the bremsstrahlung photon part of the
order-α outer (model independent) radiative correction calculations for those neutron (and …

We give a precision analysis of the correlation coefficients of the electron energy spectrum
and angular distribution of the β− decay and radiative β− decay of the neutron with polarized …

We calculate the contributions of weak magnetism and proton recoil of order O (E e 2∕ m N
2)∼ 1 0− 5, ie to next-to-next-to-leading order in the large nucleon mass expansion, to the …

In the framework of the Standard Model (SM) a theoretical description of the neutron beta
decay is given at the level of 10-5. The neutron lifetime and correlation coefficients of the …

We investigate the contributions of the hadronic structure of the neutron to radiative O (α E
e/m N) corrections [or the inner O (α E e/m N) RC] to the neutron beta decay, where α, E e …

We calculate the radiative corrections of order O (α E e/m N) as next-to-leading order
corrections in the large nucleon mass expansion to Sirlin's radiative corrections of order O …

We analyze the contributions of the one–pion–pole (OPP) exchange, caused by strong low–
energy interactions, and the pseudoscalar interaction beyond the Standard Model (BSM) to …
