Effective Action of Composite Fields for General Gauge Theories in BLT-Covariant Formalism
The gauge dependence of the effective action of composite fields for general
gauge theories in the framework of the quantization method by Batalin, Lavrov
and Tyutin is studied. The corresponding Ward identities are obtained. The
variation of composite fields effective action is found in terms of new set of
operators depending on composite field. The theorem of the on-shell gauge
fixing independence for the effective action of composite fields in such
formalism is proved. brief discussion of gravitational-vector induced
interaction for Maxwell theory with composite fields is given.Comment: Typos corrected. Latex fil
Representation of a gauge field via intrinsic "BRST" operator
We show that there exists a representation of a matrix valued gauge field via
intrinsic "BRST" operator assigned to matrix valued generators of a gauge
algebra. In this way, we reproduce the standard formulation of the ordinary
Yang - Mills theory. In the case of a generating quasigroup/groupoid, we give a
natural counterpart to the Yang - Mills action. The latter counterpart does
also apply as to the most general case of an involution for matrix-valued gauge
generators.Comment: 15 pages, no figures, Section 6 extended with (6.14), (6.15); v3:

Observation of the fine structure for rovibronic spectral lines in visible part of emission spectra of
For the first time in visible part of the emission spectrum the pseudo
doublets representing partly resolved fine structure of rovibronic lines have
been observed. They are characterized by splitting values about 0.2 cm
and relative intensity of the doublet components close to 2.0. It is shown that
they are determined by triplet splitting in lower rovibronic levels of various
electronic transitions. It is proposed to use
an existence of such partly resolved fine structure patterns for identification
of numerous unassigned spectral lines of the molecule coming from great
variety of triplet "gerade" electronic states to vibro-rotational levels of the
state.Comment: 6 pages, including 2 figures and 1 table; submitted to Phys.Rev.Let
