First constraints on general neutrino interactions based on KATRIN data
M. Aker, D. Batzler, A. Beglarian +130
The precision measurement of the tritium -decay spectrum performed by the KATRIN experiment provides a unique way to search for general neutrino interactions (GNI). All theoreti…
Direct neutrino-mass measurement based on 259 days of KATRIN data
M. Aker, D. Batzler, A. Beglarian +146
The fact that neutrinos carry a non-vanishing rest mass is evidence of physics beyond the Standard Model of elementary particles. Their absolute mass bears important relevance from…
Search for keV-scale Sterile Neutrinos with first KATRIN Data
M. Aker, D. Batzler, A. Beglarian +128
In this work we present a keV-scale sterile-neutrino search with the first tritium data of the KATRIN experiment, acquired in the commissioning run in 2018. KATRIN performs a spect…
Search for Lorentz-Invariance Violation with the first KATRIN data
M. Aker, D. Batzler, A. Beglarian +130
Some extensions of the Standard Model of Particle Physics allow for Lorentz invariance and Charge-Parity-Time (CPT)-invariance violations. In the neutrino sector strong constraints…
KATRIN: Status and Prospects for the Neutrino Mass and Beyond
M. Aker, M. Balzer, D. Batzler +159
The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to measure a high-precision integral spectrum of the endpoint region of T2 beta decay, with the primary goal of probi…
New Constraint on the Local Relic Neutrino Background Overdensity with the First KATRIN Data Runs
M. Aker, D. Batzler, A. Beglarian +129
We report on the direct cosmic relic neutrino background search from the first two science runs of the KATRIN experiment in 2019. Beta-decay electrons from a high-purity molecular…
Parity Violation in Proton-Proton Scattering at 221 MeV
A. R. Berdoz, TRIUMF E497 Collaboration
TRIUMF experiment 497 has measured the parity violating longitudinal analyzing power, A_z, in pp elastic scattering at 221.3 MeV incident proton energy. This paper includes details…
Parity Violation in Proton-Proton Scattering at 221 MeV
A. R. Berdoz, TRIUMF E497 Collaboration
The parity-violating longitudinal analyzing power, Az, has been measured in pp elastic scattering at an incident proton energy of 221 MeV. The result obtained is Az =(0.84 +/- 0.29…
Parity Violation in Proton-Proton Scattering
W. T. H. van Oers, for E497 collaboration
Measurements of parity-violating longitudinal analyzing powers (normalized asymmetries) in polarized proton-proton scattering provide a unique window on the interplay between the w…
The TRIUMF Parity Violation Experiment
W. D. Ramsay
An experiment (E497) is underway at TRIUMF to measure the angle-integrated, parity violating longitudinal analyzing power, Az, in proton-proton elastic scattering, to a precision o…
