Combined analysis of neutrino decoherence at reactor experiments
André de Gouvêa, Valentina De Romeri, Christoph A. Ternes
Reactor experiments are well suited to probe the possible loss of coherence of neutrino oscillations due to wave-packets separation. We combine data from the short-baseline experim…
Three-Body Decays of Heavy Dirac and Majorana Fermions
André de Gouvêa, Patrick J. Fox, Boris J. Kayser +1
Nonzero neutrino masses imply the existence of degrees of freedom and interactions beyond those in the Standard Model. A powerful indicator of what these might be is the nature of…
Reactor Antineutrino Oscillations at Super-Kamiokande
André de Gouvêa, Ivan Martinez-Soler
SuperKamiokande (SK) doped with gadolinium has the capability to efficiently identify electron-antineutrinos through inverse beta-decay. Given the size of SK and the number of nucl…
Searches for Decays of New Particles in the DUNE Multi-Purpose Near Detector
Jeffrey M. Berryman, André de Gouvêa, Patrick J. Fox +3
One proposed component of the upcoming Deep Underground Neutrino Experiment (DUNE) near detector complex is a multi-purpose, magnetized, gaseous argon time projection chamber: the…
On The Decaying-Sterile Neutrino Solution to the Electron (Anti)Neutrino Appearance Anomalies
André de Gouvêa, O. L. G. Peres, Suprabh Prakash +1
We explore the hypothesis that the unexplained data from LSND and MiniBooNE are evidence for a new, heavy neutrino mass-eigenstate that mixes with the muon-type neutrino and decays…
Leptonic Scalars at the LHC
André de Gouvêa, P. S. Bhupal Dev, Bhaskar Dutta +3
We explore the collider prospects of neutrino non-standard interaction with a Standard Model (SM) gauge-singlet leptonic scalar carrying two units of lepton-number-charge. Thes…
On the Impact of Neutrino Decays on the Supernova Neutronization-Burst Flux
André de Gouvêa, Ivan Martinez-Soler, Manibrata Sen
The discovery of non-zero neutrino masses invites one to consider decays of heavier neutrinos into lighter ones. We investigate the impact of two-body decays of neutrinos on the ne…
Accessible Lepton-Number-Violating Models and Negligible Neutrino Masses
André de Gouvêa, Wei-Chih Huang, Johannes König +1
Lepton-number violation (LNV), in general, implies nonzero Majorana masses for the Standard Model neutrinos. Since neutrino masses are very small, for generic candidate models of t…
Neutrino Non-Standard Interactions: A Status Report
P. S. Bhupal Dev, K. S. Babu, Peter B. Denton +23
This report summarizes the present status of neutrino non-standard interactions (NSI). After a brief overview, several aspects of NSIs are discussed, including connection to neutri…
Right-handed Sneutrinos as Nonthermal Dark Matter
Shrihari Gopalakrishna, Andre de Gouvea, Werner Porod
When the minimal supersymmetric standard model is augmented by three right-handed neutrino superfields, one generically predicts that the neutrinos acquire Majorana masses. We post…
