Type-I cosmic string network
Takashi Hiramatsu, Yuuiti Sendouda, Keitaro Takahashi, Daisuke Yamauchi, Chul-Moon Yoo
We study the network of Type-I cosmic strings using the field-theoretic numerical simulations in the Abelian-Higgs model. For Type-I strings, the gauge field plays an important role, and thus we find that the correlation length of the strings is strongly dependent upon the parameter ?, the ratio between the masses of the scalar field and the gauge field, namely, ? =?2
?/?2
?. In particular, if we take the cosmic expansion into account, the network becomes densest in the comoving box for a specific value of ? for ? <1.
