نویسنده
چکیده
We study a two-dimensional bosonic field theory with a random defect line. The theory has a background field coupled to the field variables at the defect line, which renders the model non-integrable. However, as the background field is random, and the disorder is implemented through the replica trick, the model becomes inte-grable, allowing us to use the form-factor method to compute the exact correlation functions of the quenched model.

We consider Ward’s generalized self-duality equations for U(2r) Yang-Mills theory on R and their Moyal deformation under self-dual noncommutativity. Employing an extended ADHM construction we find two kinds of explicit solutions, which generalize the ’t Hooft and BPST instantons from R to noncommutative R. The BPST-type configurations appear to be new even in the commutative case.

The Newtonian Potential is computed exactly in a theory that is fundamentally Non Commutative in the space-time coordinates. When the dispersion for the distribution of the source is minimal (i.e. it is equal to the non commutative parameter θ), the behavior for large and small distances is analyzed. PACS number: 11.10.Nx

The decay process H → γγ is examined in a model-independent way within the effective Lagrangian approach. Contribution of one-loop diagrams including SU(2) × U(1) invariant dimension-six bosonic operators is evaluated explicitly. The calculation is intended to fill a gap that exists in the current literature of the subject. [email protected] [email protected]

Brane inflation predicts the production of cosmic superstrings with tension 10 −12 < ∼ Gµ < ∼ 10 −7. Superstring theory predicts also the existence of a dilaton with a mass that is at most of the order of the gravitino mass. We show that the emission of dilatons imposes severe constraints on the allowed evolution of a cosmic super-string network. In particular, the detection of gravitational wa...

A novel low-energy neutrino-oscillation experiment NOSTOS , combining a strong tritium source and a high pressure spherical TPC detector (10 m in radius) has been recently proposed. The goal of the experiment is to measure the mixing angle θ13 , the neutrino magnetic moment and the Weinberg angle at low energy. The same apparatus , filled with high pressure Xenon , exhibits a high sensitivity a...
