Slide 5

Flavor symmetry? (Murayama) Same gage quantum numbers, yet mass order and little mixings “unnatural” (for quarks, charged leptons) Hidden quantum number? Same for neutrino eras, distinctive for charged leptons, quarks? Break flavor symmetry by little VEV Hierachies, e.g., m u :m c :m t proportion Atmospheric blending maximal+two extensive blending edges How enormous quantitatively?

Slide 7

(Fukugita) Massive neutrinos in cosmology Two applications: Leptogenesis and mass limits Evolution of expansive scale structure surely knew; enormous neutrinos sodden vacillations on skyline scale; power range! Limits from distinctive mixes of CMB, universe grouping, bunch wealth, grav. Lensing, Lyman a Limits: 2 eV (CMB alone, hearty) 0.42 eV (utilization of Lyman a ) – yet: systematics issue? Future: e.g. vast bunch overviews (> 100,000) 0.03 eV! ISS KEK Summary - Walter Winter

Slide 8

(Hisano) Flavor material science to build up SUSY? Test source of SUSY breaking terms and models past MSSM from investigations of flavor and CP infringement Charged LFV (e.g. m - > e g ) + neutrino motions give autonomous data on see-saw; vast blending edges may upgrade charged LFV ; particularly q 13 estimation would permit forecasts of charged LFV Good case for amassing reciprocal clues from diverse investigations to acquire clearer picture of material science ISS KEK Summary - Walter Winter

Slide 9

(Kuno) (Towards) hunt down charged lepton blending at NuFact Current proton drivers: 10 8 muons/s (MEG) Charged lepton blending from a wide range of models Many diff. Forms, e.g. m - > e g Some procedures locator constrained, others shaft restricted Polarized muons helpful to decrease foundations and segregate models produce e.g. by pion rot very still + change turn by intersection field Many pillar prerequisites: force, beat or persistent bar (dep. on procedure), low pion tainting, tight vitality spread 4 MW PD: 10 11-12 muons/s (PRISM) NF Frontend: 10 14 muons/s ISS KEK Summary - Walter Winter

Slide 10

(Kanemura) LFV in DIS forms Motivation: E. g. Slepton blending (SUSY) presents LFV at one circle t - related LFV fascinating for Higgs-boson interceded procedures Use DIS process: e.g. m N - > t X at neutrino manufacturing plant O(10 2 ) occasions for 50 GeV Also conceivable: neutrino bar? Cross segment increments with vitality! Accordingly: contention for as vast E m as could be expected under the circumstances Problem: Misidentification of occasions/Backgrounds; MC in advancement ISS KEK Summary - Walter Winter

Slide 11

Phenomenology (+ some Theory) … of neutrino motions Non-quickening agent neutrino property estimations Non-standard material science Is there something else past three-flavor motions? What conceivable instruments? How does one test those?

Slide 12

Prospects on n properties … from non-quickening agent sources (Choubey) D m 21 2 from KamLAND; yet wrong standard for q 12 New reactor test? Gadolinium-stacked SK for sun oriented parameters? Climatic parameters: Large magn. iron identifier? Accuracy practically identical to LBL; Also: Deviations from maximal blending, octant decadence ISS KEK Summary - Walter Winter

Slide 13

(Xing) Unitarity triangles for lepton segment Similar to quark segment: Use unitarity triangles In see-saw system: 6x6-Matrix unitary; in every single reasonable situation: dynamic blending unitary Matter impacts change unitarity triangles Example: Higher E makes sides equivalent; Easier to ascertain range Easier to build up CP viol. ISS KEK Summary - Walter Winter

Slide 14

(Sorel) Status of 3+2 plan Can suit all information Implies: Too low BG for superbeams, wrong close locator non-osc. suspicion Eventually checked by MiniBOONE !? In the event that affirmed : Some new fascinating material science: Two new fundamentally the same osc. Frequencies presented; CP infringement by distinctive stages? At that point likely new SBL trial required … ISS KEK Summary - Walter Winter

Slide 15

Slide 23

Example: d CP - execution markers Examples Allowed locale in d - q 13 - plane Identify how much parameter space stays for particular speculations of genuine qualities Sensitivity to max. CP infringement p/2 or 3 p/2 Can CP infringement be recognized for the speculation of max. CP infringement? Affectability to “any” CP infringement For what part of CP disregarding values can CP infringement be distinguished? (CP part plots)! Accuracy of d ? How absolutely can one gauge d? (just characterized in the high exactness limit, since d cyclic; likewise: not Gaussian!) CP scope How correctly can one gauge d or what portion of the parameter space can be avoided? Which one(s) valuable for ISS study? Genuine qualities: Few illustrations Purpose: Looks like result Level of buildup, calculation time Purpose: Risk minimization True values: Complete applicable space ISS KEK Summary - Walter Winter

Slide 24

Towards the presentation of results: Build solid material science case! Hypothesis required: Why are these parameters intriguing by any stretch of the imagination? Principle destinations? Discover q 13 Establish mass chain of importance Search for leptonic CP infringement Important material science limits: q 13 vast? Neutrino plant material science case? On the other hand bad habit verse: Only if q 13 little? Better finder key part? Material science for q 13 zero? For example, by some symmetry … May be essential for financing offices! E. g. mass chain of command, MSW effect… (Fig. from Huber, Lindner, Winter, hep-ph/0412199) ISS KEK Summary - Walter Winter

Slide 25
