Introduction to the "Physics Potential and Near Detectors" session

Physics Potential

We will describe sensitivity studies done after the Hyper-Kamiokande LOI by adapting the code used for sensitivity studies in T2K, first to reproduce the results of this LOI and later study the effect of using the fiTQun pi-zero rejection cut and including the muon neutrino sample, as well as requirements for the near detectors constraints.

27. HyperK sensitivity study using the VALOR T2K joint 3-flavour analysis

Mr Shah Raj (Oxford University)

Physics Potential

Will present initial results from a HyperK sensitivity study using the well-established VALOR joint 3-flavour oscillation analysis. This analysis performs simultaneous fits of the HyperK single muon-like ring and single electron-like ring event reconstructed energy distributions in a framework of 3 active neutrino oscillations including matter effects. Near detector constraints from the 2013...

20. Flux Extrapolation Uncertainties from Tokai to Hyper-K

Neutrino Beamline

Preliminary sensitivity studies for a CP violation measurement with a Tokai-to-HyperK neutrino beam suggest that 2% systematic errors are required to remain statistics limited. We investigate the uncertainty on the flux extrapolation from potential near detector sites in Tokai, including the current ND280 site and potential sites out to 2 km from the neutrino beam production point. We...

6. A New Near Detector at Intermediate Disastance for Hyper-Kamiokande

Prof. Francesca Di Lodovico (Queen Mary, University of London)

Near Detectors

A description of the studies on a new near detector at intermediate distances (around 2km or so) for Hyper-Kamiokande is presented, along with a description of the possible benefits and design.

30. The nuPRISM Near Detector: Constraining Neutrino Energy Using Multiple Off-Axis Angles

Dr Michael Wilking (TRIUMF)

Near Detectors

At the previous Hyper-K meeting, the idea for a long water Cherenkov detector that spans multiple off-axis angles was presented. Using this configuration, it is possible to constrain the relationship between lepton kinematics and neutrino energy from the neutrino beam information, rather than relying solely on model-dependent neutrino generator extrapolations. Several details of this detector...

7. LoI to J-PARC PAC

Physics Potential

Goals and schedule for the Letter of Intent to be submitted to J-PARC PAC will be discussed.

18. The DAEdALUS at Hyper-K Experiment: Searching for CP Violation

Prof. Michael Shaevitz (Columbia University)

27/01/2014, 14:20

Physics Potential

DAEdALUS is a phased program leading to a high-sensitivity search for CP violation. The experiment uses a set of high-intensity 800 MeV cyclotrons to produce pion decay-at-rest neutrino sources at several locations (with baselines of 1.5km, 8km, and 20km) going to the Hyper-K ultra-large, underground detector. The Hyper-K detector would be used to isolate and measure a very large sample of...

Physics Potential

The sensitivity of SRN in HK is reported for several cosmic ray intensity case. The cosmic muon flux in HK is also reported.
