Covariant formulation of non-Abelian gauge theories without anticommuting variables
A manifestly Lorentz invariant effective action for Yang-Mills theory
depending only on commuting fields is constructed. This action posesses a
bosonic symmetry, which plays a role analogous to the BRST symmetry in the
standard formalism.Comment: 8 pages, Late
A local gauge invariant infrared regularization of the Yang-Mills theory
A local gauge invariant infrared regularization for the Yang-Mills theory is
constructed on the basis of a higher derivative formulation of the model.Comment: 7 page
Hierarchy of massive gauge fields
An explicitely gauge invariant polynomial action for massive gauge fields is
proposed. For different values of parameters it describes massive Yang-Mills
field, the Higgs-Kibble model, the model with spontaneously broken symmetry and
two scalar mesons.Comment: 8 pages, no figure
Linear logic with idempotent exponential modalities: a note
In this note we discuss a variant of linear logic with idempotent exponential
modalities. We propose a sequent calculus system and discuss its semantics. We
also give a concrete relational model for this calculus
Lattice QCD with Exponentially Small Chirality Breaking
A new multifermion formulation of lattice QCD is proposed. The model is free
of spectrum doubling and preserves all nonanomalous chiral symmetries up to
exponentially small corrections. It is argued that a small number of fermion
fields may provide a good approximation making computer simulations feasible.Comment: 14 pages, no figures; typos correcte
A practical gauge invariant regularization of the SO(10) grand unified model
It is shown that a simple modification of the dimensional regularization
allows to compute in a consistent and gauge invariant way any diagram with less
than four loops in the SO(10) unified model. The method applies also to the
Standard Model generated by the symmetry breaking . A gauge invariant regularization for arbitrary diagram is
also described.Comment: 10 pages, uses linedraw.st
