, 1996 Recent developments in string duality suggest that the string scale may not be irrevocably tied to the Planck scale. Two explicit but unrealistic examples are described where the ratio of the string scale to the Planck scale is arbitrarily small ...

, 2014 This article discusses the status of string physics where the string tension is around the TeV scale. The article covers model building basics for perturbative strings, based on D-brane configurations. The effective low energy physics description of such

String Landscape and the Standard Model of Particle Physics
, 2007 In this paper we describe ideas about the string landscape, and how to relate it to the physics of the Standard Model of particle physics. First, we give a short status report about heterotic string compactifications. Then we focus on the statistics of D-

Zero-norm states and stringy symmetries
, 2005 We identify spacetime symmetry charges of 26D open bosonic string theory from an infinite number of zero-norm states (ZNS) with arbitrary high spin in the old covariant first quantized string spectrum.

A First Glimpse of String Theory in the Sky? [PDF]
, 2004 We propose a new method for identifying new physics imprints on present observational data in cosmology whereby signatures of string theory are clearly distinguished from imprints of possible features on the inflaton potential.

What if string theory has no de Sitter vacua? [PDF]
International Journal of Modern Physics D, 2018 We present a brief overview of attempts to construct de Sitter vacua in string theory and explain how the results of this 20-year endeavor could point to the fact that string theory harbors no de Sitter vacua at all.

Chiral symmetry restoration and the string picture of hadrons [PDF]
, 2002 QCD string picture of highly excited hadrons very naturally explains parity doubling once the chiral symmetry is restored high in the spectrum. In particular, the spin-orbit and tensor interactions of quarks at the ends of the string, related to dynamics

Unified model for vortex-string network evolution
, 2004 We describe and numerically test the velocity-dependent one-scale (VOS) string evolution model, a simple analytic approach describing a string network with the averaged correlation length and velocity.

New Directions for Adult and Continuing Education, EarlyView.ABSTRACT Nontraditional students represent a substantial number and significant percentage of students in higher education. While these adult learners have similarities, they also span 50+ years with generational differences. At the same time, online learning is on the rise, offering opportunities and challenges for nontraditional students and those ...

Noncommutative Field Theories and (Super)String Field Theories
, 2001 In this lecture notes we explain and discuss some ideas concerning noncommutative geometry in general, as well as noncommutative field theories and string field theories.
