DESCRIPTION:Speakers: Chloé Goupy (Max Planck Institute for Nuclear Physi
 cs)\n\nThe absolute mass scale of the neutrino remains one of the key open
  questions in particle physics and cosmology. The Karlsruhe Tritium Neutri
 no (KATRIN) experiment addresses this challenge by precisely measuring the
  energy spectrum of electrons from tritium beta decay near its endpoint. K
 ATRIN combines a high-intensity gaseous molecular tritium source with a hi
 gh-resolution electrostatic spectrometer with magnetic adiabatic collimati
 on. This approach has enabled KATRIN to reach sub-eV sensitivity and set a
  world-leading upper limit of 0.45 eV/c² (90% confidence level) on the ef
 fective electron anti-neutrino mass\, based on data from the first five me
 asurement campaigns. These results reflect major advancements in backgroun
 d suppression\, control of systematic uncertainties\, and statistical prec
 ision. \nIn this talk\, I will present the latest results from KATRIN\, i
 ncluding the neutrino mass analysis as well as recent results on probing t
 he eV-scale sterile neutrinos parameter space using the same experimental 
 data.\n\nhttps://indico.ijclab.in2p3.fr/event/11957/
