First-forbidden transitions in the reactor anomaly
Leendert Hayen, Joel Kostensalo, Nathal Severijns +1
We describe here microscopic calculations performed on the dominant forbidden transitions in reactor antineutrino spectra above 4 MeV using the nuclear shell model. By taking into…
Radiative corrections to Gamow-Teller decays
Leendert Hayen, Nathal Severijns
Radiative corrections in the electroweak sector constitute an essential component in the ability to disentangle Beyond Standard Model physics from experimental data. This is partic…
First-forbidden transitions in the reactor anomaly
L. Hayen, J. Kostensalo, N. Severijns +1
We study the dominant forbidden transitions in the antineutrino spectra of the fission actinides from 4 MeV onward using the nuclear shell model. Through explicit calculation of th…
Beta Spectrum Generator: High precision allowed spectrum shapes
Leendert Hayen, Nathal Severijns
Several searches for Beyond Standard Model physics rely on an accurate and highly precise theoretical description of the allowed spectrum. Following recent theoretical advances…
High precision analytical description of the allowed spectrum shape
Leendert Hayen, Nathal Severijns, Kazimierz Bodek +2
A fully analytical description of the allowed spectrum shape is given in view of ongoing and planned measurements. Its study forms an invaluable tool in the search for physics…
