3466. (I) BSM neutrino physics in weak nuclear decay

Prof. Kyle Leach (Colorado School of Mines)

Nuclear Physics / Physique nucléaire (DNP-DPN)

Invited Speaker / Conférencier(ère) invité(e)

Despite their relative complexity, unstable atomic nuclei are among the best physical systems to search for BSM neutrino physics. In particular, rare isotopes that undergo weak nuclear transitions such as $\beta$ decay, $\beta \beta$ decay, or electron capture (EC) provide a sensitive probe of a wide range of topics including neutrino masses, Majorana nature of neutrinos, and lepton number...

3322. Barium Tagging from Xe Gas as an Upgrade to the nEXO Experiment

Nuclear Physics / Physique nucléaire (DNP-DPN)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

The proposed nEXO experiment will search for neutrinoless double beta decay (0νββ) of Xe-136 in a 5-tonne enriched liquid xenon TPC. If observed, 0νββ will reveal the Majorana nature of neutrinos and show that lepton number conservation is violated in weak decays. nEXO’s sensitivity is projected to reach beyond 10^28 years (at 90% confidence level) probing for effective Majorana neutrino...

3356. (G*) Ba-ion mobility simulations in LXe for Ba-tagging at TRIUMF

Megan Cvitan (McMaster University)

Nuclear Physics / Physique nucléaire (DNP-DPN)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

The proposed nEXO experiment is a tonne-scale liquid xenon (LXe) time projection chamber that aims to uncover properties of neutrinos via the neutrinoless double beta decays (0$\nu \beta \beta$) in the isotope Xe-136. The observation of 0$\nu \beta \beta$ would point to new physics beyond the Standard Model and imply lepton number violation, indicating that neutrinos are their own antiparticle....

3326. (G*) Commissioning of a linear Paul ion trap for Ba-tagging

Mr Hussain Rasiwala (McGill University)

Nuclear Physics / Physique nucléaire (DNP-DPN)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

nEXO is a proposed 5-tonne experiment that will search for neutrinoless double-beta decay (0νββ) in liquid xenon enriched in the isotope Xe-136. Detection of such an event would significantly improve our understanding of neutrinos and potentially explain the matter-antimatter asymmetry. An observation of 0νββ would indicate the violation of the lepton number, a conserved quantity in the...

3305. (G*) Commissioning of a Multiple-Reflection Time-of-Flight Mass-Spectrometer for Barium-tagging

Nuclear Physics / Physique nucléaire (DNP-DPN)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

The proposed nEXO experiment aims to search for neutrinoless double beta decay (0$\nu \beta \beta$) in ${}^{136}$Xe with a five-tonne enriched liquid Xe time-projection chamber. The addition of barium tagging will allow for the positive identification of a candidate 0$\nu \beta \beta$ event as a true $\beta \beta$ decay, by extracting and identifying the daughter Ba ion. The nEXO collaboration is...
