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.

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

May 12 @ 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.

May 12
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.
