Neutrinoless Double Beta Decay from Singlet Neutrinos in Extra Dimensions
G. Bhattacharyya, H. V. Klapdor-Kleingrothaus, H. Päs +1
We study the model-building conditions under which a sizeable -decay signal to the recently reported level of~0.4 eV is due to Kaluza--Klein singlet neutrinos in theories wit…
Baryon and Lepton Number Violation with Scalar Bilinears
H. V. Klapdor-Kleingrothaus, E. Ma, U. Sarkar
We consider all possible scalar bilinears, which couple to two fermions of the standard model. The various baryon and lepton number violating couplings allowed by these exotic scal…
Search for Dark Matter by GENIUS-TF and GENIUS
H. V. Klapdor-Kleingrothaus
The new project GENIUS will cover a wide range of the parameter space of predictions of SUSY for neutralinos as cold dark matter. Together with DAMA it will be the only experiment…
Majorana neutrinos with split fermions in extra dimensions
H. V. Klapdor-Kleingrothaus, U. Sarkar
We propose new solutions to the neutrino mass problem in theories with large extra dimensions in a thick wall scenario. It has recently been argued that our 3-brane could be a thic…
