Bosonic superconducting cosmic strings

Physical Review D, 1988
We study the classical solutions of bosonic superconducting strings for quartic and Coleman-Weinberg effective potentials. We map the parameter space of solutions, and discuss and quantify back reaction of the charged condensate upon the vortex. We address the issue of the critical current and the quench transition.

String Theory: Bosonic String

2021
What we have achieved so far is not entirely satisfactory: Supersymmetry (more precisely, the broader framework of supergravity) offers a partial solution to the weak-scale hierarchy problem. Partial refers to the fact that SUSY partners have not been discovered (yet?) and hence some fine-tuning is probably needed after all.

K27 as a symmetry of closed bosonic strings and branes

International Journal of Modern Physics A
We show that the dynamics encoded in the non-linear realisation of the semi-direct product of the very extended algebra K27 with its vector representation contains the low energy effective action of the closed bosonic string.

Closed strings from open bosonic strings

Physical Review D, 1989
We show that closed strings can be incorporated into a bosonic open-string theory by a suitable enlargement of the open-string Fock space. We present an explicit construction of the states in this space in terms of open-string oscillators. The couplings between closed- and open-string states are those deduced from factorization over the closed-string ...

Improved model of bosonic string

Physical Review D, 1987
A model of the bosonic string is presented in which 16 additional twisted scalar fields defined on the world sheet allow the tachyonic mass to vanish and scalar fields defined on the world sheet allow the tachyonic mass to vanish and the critical dimension to be lowered to d=10.
