Diphoton Excess as a Hidden Monopole
We provide a theory with a monopole of a strongly-interacting hidden U(1)
gauge symmetry that can explain the 750-GeV diphoton excess reported by ATLAS
and CMS. The excess results from the resonance of monopole, which is produced
via gluon fusion and decays into two photons. In the low energy, there are only
mesons and a monopole in our model because any baryons cannot be gauge
invariant in terms of strongly interacting Abelian symmetry. This is
advantageous of our model because there is no unwanted relics around the BBN
epoch.Comment: 6 pages, 1 figur
String matching problems over free partially commutative monoids
AbstractThis paper studies two string matching problems over free partially commutative monoids. We analyze these two problems in detail, and present two efficient polynomial time algorithms for solving them
Dark baryon from pure Yang-Mills theory and its GW signature from cosmic strings
We point out that SO() pure Yang-Mills theory provides a candidate for
dark matter (DM) without the explicit need to impose any additional symmetry.
The DM candidate is a particular type of glueball, which we refer to as a
baryonic glueball, that is naturally stable for a moderately large . In this
case, the intercommutation probability of cosmic strings (or macroscopic color
flux tubes) is quite low, which offers characteristic gravitational wave
signals to test our model. In particular, our model can simultaneously account
for both abundance of DM and the recently reported gravitational wave signals
detected in pulsar timing array experiments, including NANOGrav.Comment: 7 pages, 1 figur
