چکیده
We consider a two-form antisymmetric tensor field φ minimally coupled to a nonabelian vector field with a field strength F . Canonical analysis suggests that a pseudoscalar mass term μ 2 2 Tr(φ∧φ) for the tensor field eliminates degrees of freedom associated with this field. Explicit one loop calculations show that an additional coupling mTr(φ ∧ F ) (which can be eliminated classically by a tensor field shift) reintroduces tensor field degrees of freedom. We attribute this to the lack of the renormalizability in our vector-tensor model. We also explore a vector-tensor model with a tensor field scalar mass term μ 2 2 Tr(φ ∧ ⋆φ) and coupling mTr(φ ∧ ⋆F ). We comment on the Stueckelberg mechanism for mass generation in the Abelian version of the latter model.

A new class of models of dynamical supersymmetry breaking is proposed. The models are based on SU(NC) gauge theories with NF (< NC) flavors of quarks and singlets. Dynamically generated superpotential exibits runaway behavior. By embedding the models into conformal field theories at high energies, the runaway potential is stabilized by strong quantum corrections to the Kähler potential. The qua...

We investigate the viability of F-term uplift in heterotic M-theory. With this aim we explore a natural ingredient of heterotic compactifications, namely vector bundle moduli. It is shown that it is generically possible to obtain stable de Sitter vacua with broken supersymmetry provided the little Kähler potential and the prefactors of the non-perturbative superpotential are suitably tuned. An ...

We study the entanglement of two disjoint intervals in the conformal field theory of the Luttinger liquid (free compactified boson). Trρ A for any integer n is calculated as the four-point function of a particular type of twist fields and the final result is expressed in a compact form in terms of the Riemann-Siegel theta functions. In the decompactification limit we provide the analytic contin...

A formulation of U(1) symmetric classical membrane motions (preserving one rotational symmetry) is given, and reductions to systems of ODE’s, as well as some ideas concerning singularities and integrability. Let me start by giving some particular example(s) of a 2-dimensonal (timelike, time periodic) extremal manifold M2 ⊂ R and 3-folds (singularities included) of vanishing mean curvature, in 4...
