Thraxions: towards full string models [PDF]

Journal of High Energy Physics, 2022
We elucidate various aspects of the physics of thraxions, ultra-light axions arising at Klebanov-Strassler multi-throats in the compactification space of IIB superstring theory.

String Bit Models for Superstring [PDF]

Physical Review D, 1995
We extend the model of string as a polymer of string bits to the case of superstring. We mainly concentrate on type II-B superstring, with some discussion of the obstacles presented by not II-B superstring, together with possible strategies for ...

Statistical Relational Learning With Unconventional String Models [PDF]

Frontiers in Robotics and AI, 2018
This paper shows how methods from statistical relational learning can be used to address problems in grammatical inference using model-theoretic representations of strings.

BFKL Pomeron in string models [PDF]

Nuclear Physics B, 2006
We consider scattering amplitudes in string models in the Regge limit of high energies and fixed momentum transfers with the use of the unitarity in direct channels.

Minimal Standard Heterotic String Models [PDF]

The European Physical Journal C, 2006
Three generation heterotic-string vacua in the free fermionic formulation gave rise to models with solely the MSSM states in the observable Standard Model charged sector.

Topological Strings from WZW Models [PDF]

Physics Letters B, 1994
We show that the BRST structure of the topological string is encoded in the ``small'' $N=4$ superconformal algebra, enabling us to obtain, in a non-trivial way, the string theory from hamiltonian reduction of $A(1|1)$.

Counting string theory standard models

Physics Letters B, 2019
We derive an approximate analytic relation between the number of consistent heterotic Calabi-Yau compactifications of string theory with the exact charged matter content of the standard model of particle physics and the topological data of the internal ...

String Phenomenology: Past, Present and Future Perspectives [PDF]

Galaxies, 2014
The observation of a scalar resonance at the Large Hadron Collider (LHC), compatible with perturbative electroweak symmetry breaking, reinforces the Standard Model (SM) parameterisation of all subatomic data. The logarithmic evolution of the SM gauge and

String breaking in a cold wind as seen by string models

Nuclear Physics B, 2022
Using the gauge/string duality, we model a heavy quark-antiquark pair in a color singlet state moving through a cold medium and explore the consequences of temperature and velocity on string breaking. In doing so, we restrict to the case of two dynamical
