Residual symmetries in the lepton mass matrices
Walter Grimus
It has been suggested that residual symmetries in the charged-lepton and neutrino mass matrices can possibly reveal the flavour symmetry group of the lepton sector. We review the b…
Correlations and textures in the neutrino mass matrix
Walter Grimus, Patrick Otto Ludl
The recent enormous improvement of our knowledge of the neutrino oscillation parameters has motivated us to reinvestigate the allowed ranges of the elements of the neutrino mass ma…
Double seesaw mechanism and lepton mixing
W. Grimus, L. Lavoura
We present a general framework for models in which the lepton mixing matrix is the product of the maximal mixing matrix U_ω times a matrix constrained by a well-defined Z_2 symmetr…
Doubly charged scalar decays in a type II seesaw scenario with two Higgs triplets
Avinanda Chaudhuri, Walter Grimus, Biswarup Mukhopadhyaya
The type II seesaw mechanism for neutrino mass generation usually makes use of one complex scalar triplet. The collider signature of the doubly-charged scalar, the most striking fe…
Discrete symmetries, roots of unity, and lepton mixing
Walter Grimus
We investigate the possibility that the first column of the lepton mixing matrix U is given by u_1 = (2,-1,-1)^T/sqrt{6}. In a purely group-theoretical approach, based on residual…
