Journal Article

Based on a binary tree model for the self-intersection of cosmic string loops containing high harmonics we estimate the number of self-intersections of the parent and daughter loops and the associated cusp production to determine the most likely numb...

Journal Article

We consider the higher order clockwork theory of gravitational interactions, whereby a number of gravitons are coupled together with TeV strength, but nevertheless generate a Planck scale coupling to matter without the need for a dilaton. It is shown... Read More about Deconstructing higher order clockwork gravity.

Cusp properties of high harmonic loops (2021)
Journal Article
Pazouli, D., Avgoustidis, A., & Copeland, E. J. (2021). Cusp properties of high harmonic loops. Physical Review D, 103(6), Article 063536. https://doi.org/10.1103/physrevd.103.063536

In determining the gravitational signal of cusps from a network of cosmic string loops, a number of key parameters have to be assumed. These include the typical number of cusps per period of string oscillation and the typical values of the sharpness... Read More about Cusp properties of high harmonic loops.
