Lorentz Invariance and the Cosmological Constant - Bertolami (1997) Self-citation (Bertolami) (Correct)
.... of the baryon asymmetry of the Universe as the tensor fermionfermion interactions (see below) give origin, after the breaking of the Lorentz and CPT symmetries, to a chemical potential that creates in equilibrium a baryon antibaryon asymmetry in the presence of baryon number violating interactions [17]. The main argument in favour of the breaking of the Lorentz invariance arises in the bosonic open string field theory where interactions are trilinear type [18] The static potential in this string field theory proposal has the following form [5] V (S i ; T i M ) 1 2 X i;j m 2 ij ....
....compared with experimental limits. However, in order to better quantify this we have actually to consider the coupling of Lorentz tensor fields to fermions via the trilinear string field interactions. These are actually, the relevant couplings when studying CPT violation [14, 15] and baryogenesis [17]. The most general form for these interactions is the following: L I = T M k ( Gamma) k 1 (i ) k h:c: 5) where is a dimensionless coupling constant, and denote generic fermionic fields, Gamma denotes a gamma matrix structure, i ) k represents the action of a ....
