A more effective QCD string at colliders: Decay of excited strings and the worldsheet axion
Ethan Carragher, John March-Russell
The confining flux tube of d QCD is described by an effective string theory with d worldsheet action that extends the Nambu-Goto form by the addition of a massive pse…

Metastable cosmic strings are broken at the start
Lorenzo Tranchedone, Ethan Carragher, Edward Hardy +1
We show that metastable cosmic strings break at early times, either via finite-temperature effects or by attaching to pre-existing monopoles during network percolation. The resulti…
