A model of neutrino mass and dark matter with large neutrinoless double beta decay

open access: yesJournal of High Energy Physics, 2017
We propose a model where neutrino masses are generated at three loop order but neutrinoless double beta decay occurs at one loop. Thus we can have large neutrinoless double beta decay observable in the future experiments even when the neutrino masses are

Bound-state dark matter with Majorana neutrinos

open access: yesPhysics Letters B, 2019
We propose a simple scenario in which dark matter (DM) emerges as a stable neutral hadronic thermal relic, its stability following from an exact U(1)D symmetry.

Reconstructing neutrinoless double beta decay event kinematics in a xenon gas detector with vertex tagging

open access: yesJournal of High Energy Physics
If neutrinoless double beta decay is discovered, the next natural step would be understanding the lepton number violating physics responsible for it. Several alternatives exist beyond the exchange of light neutrinos.

Search for double beta decay of 136Xe to the 0 1 + $$ {0}_1^{+} $$ excited state of 136Ba with PandaX-4T

open access: yesJournal of High Energy Physics
We perform a search of double beta decay of 136Xe to the excited state, 0 1 + $$ {0}_1^{+} $$ , of 136Ba (2νββ- 0 1 + $$ {0}_1^{+} $$ ), using the dual-phase xenon detector of PandaX-4T with the first 94.9-day commissioning data.

Exploring X-ray lines as scotogenic signals

open access: yesPhysics Letters B, 2014
We consider some implications of X-ray lines from certain astronomical objects as potential effects of dark matter decay in the context of the scotogenic model, where neutrinos acquire mass radiatively via one-loop interactions with dark matter.

An accurate solar axions ray-tracing response of BabyIAXO

open access: yesJournal of High Energy Physics
BabyIAXO is the intermediate stage of the International Axion Observatory (IAXO) to be hosted at DESY. Its primary goal is the detection of solar axions following the axion helioscope technique. Axions are converted into photons in a large magnet that is

Electroluminescence TPCs at the thermal diffusion limit

open access: yesJournal of High Energy Physics, 2019
The NEXT experiment aims at searching for the hypothetical neutrinoless double-beta decay from the 136Xe isotope using a high-purity xenon TPC. Efficient discrimination of the events through pattern recognition of the topology of primary ionisation ...

Li-containing scintillating bolometers for low background physics

open access: yesEPJ Web of Conferences, 2014
We present the performances of Li-based compounds used as scintillating bolometer for rare decay studies such as double-beta decay and direct dark matter investigations.

Searching for millicharged particles with 1 kg of Skipper-CCDs using the NuMI beam at Fermilab

open access: yesJournal of High Energy Physics
Oscura is a planned light-dark matter search experiment using Skipper-CCDs with a total active mass of 10 kg. As part of the detector development, the collaboration plans to build the Oscura Integration Test (OIT), an engineering test with 10% of the ...
