Institute for Nuclear and Particle Astrophysics (INPA) at LBNL
The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room, located in Bldg. 50A- 5132.
The committee members are:
The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.
Please send all suggestions for future INPA talks and speakers to the INPA Committee.

INPA SEMINAR TALK
Date: July 19th
Time: 12:00 pm – 1:00 pm
Location: Sessler Conference Room – 50A-5132 [Hybrid and In-Person]
Speaker: Kenny Vetter (UC Berkeley)
Title: Quieting the Chaos in the Cold: Noise Cancellation Algorithms in CUORE’s Search for 0νββ Decay
Abstract: Neutrinos have puzzled physicists for decades despite significant strides in understanding them over the past thirty years, with many questions about their masses still remaining. The fact that neutrinos are indeed massive has shown that the Standard Model of particle physics, while wildly successful, is incomplete. This has motivated searches for Beyond Standard Model processes that may fundamentally change our understanding of nature. Among these potential processes is neutrinoless double beta decay $(0\nu\beta\beta)$, a theorized lepton number violating process. Experimental evidence of $0\nu\beta\beta$ decay would conclusively show that neutrinos are Majorana fermions. The Cryogenic Underground Observatory for Rare Events (CUORE) experiment is an ongoing search for $0\nu\beta\beta$ decay in $^{130}$Te. This talk will showcase the improvement in the CUORE data quality with a novel noise cancellation algorithm and detail the application of this algorithm to CUORE’s latest dataset with 2039 kg·yr of TeO$_2$ exposure. I will also report the results from CUORE’s search for $0\nu\beta\beta$ decay using this dataset. We find no evidence for $0\nu\beta\beta$ decay, and we place a lower limit on the half-life of $T_{1/2}^{0\nu} > 3.8 \times 10^{25}$ yr. Finally, I will discuss future searches for $0\nu\beta\beta$ decay beyond CUORE and how they will profit from future noise decorrelation algorithms.
