String Amplitudes

We discuss string amplitudes, in particular tree amplitude of bosonic open strings, using an approximated vertex of the light-cone field theory from the point of view of high energy.

Symmetry Structure

It is known that infinitely many linear relations among string scattering amplitudes appear in high energy limit. These linear relations would imply a symmetry structure that is not manifest before taking the high energy limit. Motivated by this observation, we study an effective field theory of massive spin-2 and spin-1 particles, and try to understand what kind of structure reproduces the linear relations among the amplitudes of bosonic open string.

Thermally Activated

I review various strong field problems in field theory. I start with one of the earliest examples, a high Z Coulomb field. I discuss tunneling and thermally activated transitions in field theory. The latter problem may have applications to electroweak baryogenesis. Finally, I discuss the Color Glass Condensate, a form of high energy density gluonic matter which controls the high energy limit of QCD, and the Glasma which it makes in the collision of high energy nuclei.

Topological Field

A SL (5, ℝ) gauge-invariant topological field theory of gravity and possible gauge unifications are considered in four-dimensions (4D). The problem of quantization is evaluated in the asymptotic safety scenario. "Minimal" BF type models for the high energy limit are physically not quite realistic, a tiny symmetry breaking is needed to recover standard Einsteinian gravity for the macroscopic metrical background with induced cosmological constant.

We briefly review some selected topics in the small x physics. In particular, we discuss the progress in the problem related to the resummation at small x and the parton saturation phenomena. Finally we discuss some phenomenological applications to deep inelastic scattering, hadron and heavy ion collisions.
