The theory unifying spin and charges and predicting families, proposed as a new way to explain the assumptions of the standard model of the electroweak and colour interactions, predicts at the low ene...
Can the matter-antimatter asymmetry be easier to understand within the "spin-charge-family-theory", predicting twice four families and two times $SU(2)$ vector gauge and scalar fields?

2011/1/10
We present an analysis of the spin and orbital properties of the newly discovered accreting pulsar IGR J17480-2446, located in the globular cluster Terzan 5. Considering the pulses detected by the Ros...

Electromagnetic properties non-Dirac particles
2010/12/27
We resolve a number of questions related to an analytic description of electromagnetic form factors of non-Dirac particles with the rest spin 1/2. We find the general structure of a matrix antisymmetr...
