Signal of the pion string at high-energy collisions
Tao Huang, Yunde Li, Hong Mao +2
We study the possible signals of a pion string associated with the QCD chiral phase transition in LHC Pb - Pb collision at energy TeV. In terms of the Kibble-Zurek…
Stabilization of the Electroweak Z String in the Early Universe
Michiyasu Nagasawa, Robert Brandenberger
The standard electroweak theory admits a string solution, the Z string, in which only the electrically neutral Higgs fields are excited. This solution is unstable at zero temperatu…
Formation of multiple winding topological defects in the early universe
Takahiro Okabe, Michiyasu Nagasawa
The formation probability of multiple winding topological defects is calculated by phase and flux distribution analysis based on the Kibble mechanism. The core size of defects is t…
Stabilization of Embedded Defects by Plasma Effects
M. Nagasawa, R. Brandenberger
In models in which some of the scalar field are charged and some uncharged, interactions with a finite temperature plasma will lead to corrections to the effective potential of the…
A New Regime for Dense String Networks in the One Scale Model with Friction
Charanjit S. Aulakh, Michiyasu Nagasawa, Vikram Soni
We examine the compatibility between the one scale model with friction for the evolution of cosmic string networks with the Kibble mechanism for string network formation during a s…
Scaling Distribution of Axionic Strings and Estimation of Axion Density from Axionic Domain Walls
Michiyasu NAGASAWA
The damping of the axionic string motion due to the surrounding plasma is estimated by a detailed calculation of the fermion scatter from a global string and it is shown that the f…
