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.

Speaker: Raquel Castillo Fernandez (University of Texas Arlington)- Title: In the hunt for 0νββ at the NEXT experiment

May 12, 2023 @ 12:00 pm - 1:00 pm

This is an In-Person [HYBRID] Event

LOCATION: Sessler Conference Room – 50A – 5132

DATE: May 12, 2023

TIME: 12:00- 1:00 PM

TITLE: In the hunt for 0νββ at the NEXT experiment

ABSTRACT: In the last decades, oscillation experiments have demonstrated that neutrinos are not massless particles, and the lepton number is not conserved. Thus, revealing the nature of neutrino masses is one of the major goals in particle physics, and the observation of the neutrinoless double beta decay (0νββ) has been identified as the most practical way to establish that neutrinos are Majorana particles, that is, fermions equivalent to their antiparticles. However, 0νββ, which would violate the lepton number by two units, has not been observed yet and the best limits to the half-life of this process exceed 10ˆ26 yr. An extraordinary effort by several experimental collaborations is ongoing to achieve this ambitious goal and to explore the possibilities to understand the underlying physics of this process, among them, the NEXT experiment aims at the competitive search for the 0νββ decay in 136Xe using high-pressure gas electroluminescent time projection chambers (TPCs). In this talk, I will discuss the status of the current prototypes that are under installation, NEXT-100 and NEXT-CRAB, and some of the main challenges and virtues of the 0νββ search.
