High Spins Beyond Rarita-Schwinger Framework
Mariana Kirchbach, Mauro Napsuciale
We study the eigenvalue problem of the squared Pauli-Lubanski vector, W^{2}, in the Spinor-Vector representation space and derive from it that the -s(s+1)m^{2} subspace with s=3/2,…
Neutral Fermion Phenomenology With Majorana Spinors
M. Kirchbach, C. Compean, L. Noriega
We ask the question whether neutrino physics with momentum space Majorana spinors, the eigenvectors of the particle--antiparticle conjugation operator, C=iγ_2 K (with K standing fo…
Spacetime Structure of Massive Gravitinos
M. Kirchbach, D. V. Ahluwalia
The talk presents an ab initio construct of the spacetime structure underlying massive gravitinos. We argue that single spin interpretation of massive gravitino is untenable, and t…
Comment on ``Mixing and Decay Constants of Pseudoscalar Mesons''
M. Kirchbach
The key assumption used recently by Feldmann, Kroll and Stich [Phys.Rev. D58, 114006 (1998)] that the decay constants f_η, and f_η' of the respective eta and eta ' mesons in the qu…
Baryons As Hyperspherical O(4) Partial Waves -- Is This The Message From The Spectra?
M. Kirchbach
It is argued that the baryon excitations group to four-dimensional partial waves described by means of the three Rarita-Schwinger (RS) fields [(σ-1 )/2 ,(σ-1)/2]* [(1/2, 0)+(0,1/2)…
Anomalous Hypercharge Axial Current And The Couplings Of The eta And f_1 (1420) Mesons To The Nucleon
S. Neumeier, M. Kirchbach
It is argued that the precise three flavor symmetry of hadrons is not SU(3)_F but rather U(4)_F restricted to SU(2)_{ud}*SU(2)_{cs}*U(1) and considered in the limit of frozen charm…
