Recent observations could be explained by oscillations of massive neutrinos.

Many Remaining Problems

• really oscillations ?• sensitive to m2

• Masses of Neutrino • Nature of Neutrino

• Dirac• Majorana

Neutrinoless Double -Decay

• Direct Mass Measurements are indicated Spectrometer

Cobra - The idea

Use large amount of CdTe (CdZnTe) Semiconductor Detectors

K. Zuber, Phys. Lett. B 519,1 (2001)

Detector array

7 isotopes (especially 116Cd and 130Te)

10 kg CdTe (upgrade easily possible)

Mass limits for both below 1 eV

Future option: Pixel CdTe (Tracking)Isotopical enrichment

Study of double electron capture modes

First results: nucl-ex/0301007

Many approaches to neutrinoless double -decay

Are there attempts to collaborate

and concentrate ?

What is best CPT test ?

New Ansatz (Kostelecky)

• K0 10-18 GeV/c2

• n 10-30 GeV/c2

• p 10-24 GeV/c2

• e- 10-27 GeV/c2

• Future:

Anti hydrogen 10-18 GeV/c2

often quoted:

• K0- K0 mass difference (10-18)

• e- - e+ g- factors (2* 10-12)

• We need an interaction with a finite strength !
