About the INPA Seminars

All seminars are on Fridays (unless otherwise noted) and start at 12:00 (noon) with a brief presentation of the weekly scientific news. Typically the talks end by 13:00. The seminars take place in Bldg. 50A, room 5132.

The committee members are:

The following Seminar schedule for the Institute for Nuclear and Particle Astrophysics is tentative. The seminar becomes final usually a few days before the Friday of the talk.

TITLE: Investigation of the Majorana nature of neutrinos at a few meV level of the neutrino mass scale: from CUPID to BINGO

ABSTRACT: The search for neutrinoless double beta decay (0ν2β) is one of the biggest experimental challenges of contemporary physics. Its discovery would be ground- breaking since it would prove the Majorana nature of neutrinos, give an insight into neutrino mass scale, and provide clues to explain the matter/antimatter asymmetry of our Universe. Cryogenic calorimeters are promising devices for this purpose as CUORE, the ton-scale experiment constructed with such detectors, is demonstrating by setting the most stringent limit on Te-130 0ν2β half-life and being one of the most sensitive current generation experiments. However, its sensitivity is limited by the background. Its successor, the next-generation experiment CUPID, will reach a higher sensitivity by reducing the number of expected background events in the region of interest. It will study as the candidate isotope Mo-100 embedded inside Li2MoO4 scintillating crystals, which allows mitigating the Ɣ background naturally while also introducing a dual heat/light readout using an auxiliary Ge bolometer to get rid of the α background. Thanks to that, CUPID will improve the CUORE sensitivity by two orders of magnitude. At that point, if 0ν2β still eludes us, the background reduction must be pushed even further. BINGO is a project aiming to prepare the next-next generation of bolometric experiments by proposing innovations and methods for that purpose. For example, it will reduce the remaining Ɣ and β background contributions thanks to respectively a cryogenic active veto and a revolutionary detector assembly. BINGO will demonstrate that, once implemented in a ton-scale isotope experiment, its improvements will allow the latter to reach a sensitivity to neutrino mass scale below 10 meV. In that talk, the current status of the CUPID experiment will be discussed and the R&D work done in the framework of the BINGO project will be presented.

May 5
12:00 pm - 1:00 pm

INPA guests from campus can now come up to the lab early on Fridays. The INPA Common Room (50-5026) is reserved for our guests from 10:00 am to 12:00 noon, and from 1 pm to 5 pm. Note that the seminars are now held in 50A-5132 to accommodate a larger number of attendees.

Also, on Fridays from 1:00 pm to 2:00 pm you are welcome to join the INPA Speaker for a brown-bag lunch in the small Pers Hall conference room, 54-130B.

INPA Tea Series

The Physics and Nuclear Science Divisions have together been leaders in revolutionary changes in our understanding of neutrinos and cosmology. Everyone is welcome to attend the open forum. Tea and light refreshments will be served.
