339. Neutrino mass spectrum from the seesaw mechanism with the second Higgs doublet added

Dr Darius Jurciukonis (Vilnius University, Institute of Theoretical Physics and Astronomy)

Theory / Phenomenology

Poster

Neutrino oscillation experiments showed that neutrinos have tiny but non-zero masses. The seesaw mechanism is the most fruitful explanation of the light neutrino masses and mixings, which connects the tiny neutrino masses with heavy right-handed neutrino masses. After spontaneous symmetry breaking of the Standard Model gauge group one obtains a (n_L+n_R) x (n_L+n_R) Majorana mass matrix M_nu...

After successful 20 year long program to set an upper limit for the electron antineutrino mass the Troitsk experiment gets a new breath. Tritium beta-decay allows to search for a new physics - a possible contribution of sterile neutrinos to the electron spectrum. Sterile neutrino in keV mass range is a good candidate for the Warm Dark Matter. Our new goal is to measure beta-spectrum in the...

279. Underground Muon Flux in Daya Bay and JUNO experiments

Dr Jilei Xu (IHEP, China)

Reactor Neutrino Oscillations

Poster

Muon induced background is one of the main backgrounds of the Daya Bay experiment and is also critical for JUNO background estimation, sensitivity studies and detector design. This background can be estimated by the muon flux at each experimental site, which is estimated by simulation with MUSIC, the Daya Bay mountain profile and a modified Gaisser formula at sea level. The underground muon...

99. Unfolding of the Muon Neutrino Energy Spectrum with IceCube

Mr Martin Schmitz (TU Dortmund)

Cosmic Neutrinos

Poster

We present preliminary results on the energy unfolding of muon neutrinos with the IceCube Neutrino Observatory in its 79-string configuration. For the unfolding we derived a sample of high-quality muon neutrinos with a purity of above 99.2% using a random forest. Within the software TRUEE the unfolding was performed with a Tikhonov regularization and it covers an energy range of more than 4...

8. Unitarity constraints for Yukawa couplings in the SU (2)L × U (1)Y × U (1)B−L model

Prof. Andrés Fernando Castillo Ramirez (Universidad Nacional de Colombia)

Theory / Phenomenology

Poster

Constraints from unitarity perturbativity are studied in the Yukawa sector of a SU (2)L × U (1)Y × U (1)B−L model. In this scenario, besides three right handed neutrinos which are included to cancel chiral anomalies, it is also postulated a complex scalar singlet for the spontaneous symmetry breaking of the extended gauge sector U (1)B−L and to give mass to the associated Z ′ boson. From...

45. Updated three-neutrino oscillation parameters from global fits

Dr Mariam Tortola (IFIC - CSIC / Universitat de Valencia)

Theory / Phenomenology

Poster

In this work we present an updated global fit to neutrino oscillation data within the three-flavour framework. The most recent data from solar and atmospheric neutrino experiments are included in our analysis together with the latest results from the long-baseline accelerator experiments T2K and MINOS and the recent measurements of reactor neutrino disappearance reported by Double Chooz,...

322. Upper bound on neutrino mass with T2K

Thomas Kutter (LSU)

Neutrino Mass

Poster

The Tokai to Kamioka (T2K) long-baseline neutrino experiment has conclusively demonstrated the appearance of electron neutrinos in a nearly pure beam of muon neutrinos. The T2K experiment also performed precise measurements of neutrino oscillation parameters in the muon neutrino dis-appearance channel and cross-section measurements with the near detector. The present work utilizes the T2K...

324. Using Fast Photosensors in Massive Water Cherenkov Neutrino Detectors

Dr Ioana Anghel (Iowa State University/Argonne National Lab)

Neutrino Interactions

Poster

Future experiments rely on the precision measurements of rare events with low cross section, such as neutrino interactions and proton decay. Using very large detectors and new advances in photosensor technology are both important towards the achievement of high sensitivity to these measurements. New photodetectors based on micro-channel plates are being developed by the Large-Area Picosecond...

307. Viability Test of 20-cm Hybrid Photodetector in a Water Cherenkov Detector

Dr Yasuhiro NISHIMURA (RCCN, ICRR, The University of Tokyo)

Atmospheric Neutrinos

Poster

New photodetectors utilizing semiconductor electronics or improved detection efficiency are expected to increase physics sensitivity in future neutrino experiments. In order to assess the usability of the new photodetectors in a water Cherenkov detector, we started a viability test with a hybrid photodetector (HPD). The HPD has a 20-cm diameter, and is equipped with an avalanche diode. In...

148. Waveform Denoising in EXO-200

Clayton G. Davis (University of Maryland)

Neutrinoless Double Beta Decay

Poster

Neutrinoless double-beta decay experiments search for a rare mono-energetic decay process. Their sensitivity is determined in part by their energy resolution. The EXO-200 experiment searches for neutrinoless double-beta decay of xenon-136 and has a resolution which is limited by noise in the scintillation channel. Here we present a new technique for denoising the scintillation waveforms in...

335. π+ and π- mutliplicities measured in p+C interactions at 31GeV/c in NA61/SHINE for the T2K experiment.

Dr Magdalena Posiadala (University of Warsaw)

Neutrino Beam Flux

Poster

The T2K (Tokai-to-Kamioka) is a second generation long baseline neutrino oscillation experiment which, for the first time in the world, was able to detect νμ−>νe appearance [1] and as a result the oscillation parameter θ13 could be measured. The T2K neutrino beam predictions require knowledge of the hadron production in proton-carbon interactions at 31 GeV/c. The NA61/SHINE (SHINE =...
