abstract

We study the spectrum of loops as a part of a complete network of cosmic strings in flat spacetime. After a long transient regime, characterized by production of small loops at the scale of the initial conditions, it appears that a true scaling regime takes over. In this final regime the characteristic length of loops scales as $0.1 t$, in contrast to earlier simulations which found tiny loops. We expect the expanding-universe behavior to be qualitatively similar. The large loop sizes have important cosmological implications. In particular, the nucleosynthesis bound becomes $G\mu \lesssim 10^{-7}$, much tighter than before.

  1. Gravitational Wave Imprints of a High-Quality Axion and the Origin of Flavor Hierarchies

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    Gauged U(1)_F flavor symmetries shield the axion from quantum gravity corrections, yielding unit domain wall number and a plateau-valley GW spectrum from flavonic and axionic strings as a probe of flavored axion dark matter.

  2. Cogenesis of baryon and lepton number asymmetries matching the EMPRESS Data

    hep-ph 2025-09 conditional novelty 5.0 of 10

    A U(1)_{B-L} flaton decay chain can produce both a large positive electron-neutrino asymmetry and the observed baryon asymmetry, with values matching EMPRESS and BBN for a symmetry-breaking scale around 10^10 GeV.

  3. Not-quite-primordial black holes seeded by cosmic string loops

    astro-ph.CO 2025-07 conditional novelty 5.0 of 10

    Cosmic string loops moving through the early universe can seed halos that collapse into 10^5 solar mass black holes, potentially explaining JWST's little red dots.

  4. Monopoles, Strings, Walls and Gravitational waves

    hep-ph 2026-07 conditional novelty 4.0 of 10

    Breaking SU(2) flavor gauge symmetry stepwise to nothing leaves monopoles, strings, and walls; collapsing walls can form composite strings whose gravitational-wave spectra fit PTA data and lie within reach of LVK and ...

  5. Magnetic monopoles and high frequency gravitational waves from quasi-stable strings

    hep-ph 2026-03 conditional novelty 4.0 of 10

    SO(10) breaking through flipped SU(5) or Pati-Salam subgroups can produce GUT monopoles from merging monopole-antimonopole pairs, while the intervening quasi-stable strings emit gravitational waves from Hz to kHz.

  6. C-parity, magnetic monopoles and higher frequency gravitational waves

    hep-ph 2025-02 conditional novelty 4.0 of 10

    The C-string-wall network from SO(10) breaking with unbroken C-parity produces a gravitational wave background peaking between 100 Hz and 100 kHz for intermediate breaking scales around 10^10 to 10^12 GeV.
