Mini-bangs in KATRIN to explore the big one!

Mini-bangs in KATRIN to explore the big one!
The analysis on data recorded in 2019, led by an IRFU physicist, on relic neutrinos improves on previous limits by two orders of magnitude.
The cosmic background neutrino is one of the predictions of the standard cosmological model, but it has never been directly observed. These so-called "relic neutrinos" could be captured on a radioactive nucleus like tritium.

KATRIN steps up efforts in the search for the sterile neutrino
The KATRIN collaboration has just recently reported a new upper limit of 0.8 eV/c2 on the mass of neutrinos. The KATRIN spectrometer also has a strong potential to search for new, so-called "sterile" neutrinos, based on a fine analysis of the tritium beta decay spectrum.

KATRIN experiment breaks new neutrino mass record at less than 0.8 eV
KATRIN has just crossed a symbolic threshold and reveals a new upper limit!
The KATRIN (KArlsruhe TRItium Neutrino Experiment) located at the Karlsruhe Institute of Technology (KIT) has just crossed a symbolic threshold. In a paper published in the prestigious journal Nature Physics, the collaboration reveals a new upper limit of 0.8 eV/c^2 for the mass of neutrinos.

KATRIN: a still unsterilized scale!
The main objective of the KATRIN experiment is the measurement of the mass of the three neutrinos of the Standard Model of Particle Physics. But the analysis of the beta decay spectrum of tritium also allows to search for the trace of a hypothetical fourth neutrino, called sterile neutrino.

First injection of tritium in the KATRIN experiment
What is the mass of neutrinos? To answer this fundamental question, the KATRIN experiment was designed and built by an international collaboration at the Karlsruhe Institute of Technology. On June 11, 2018, an international symposium marked the beginning of data acquisition.
