Dark Revelations of the and Gauge Extensions of the Standard Model
Two theoretically well-motivated gauge extensions of the standard model are
and , where is the same as and
is its color leptonic counterpart. Each as three variations, according to how
is broken. It is shown here for the first time that a built-in dark
gauge symmetry exists in all six versions, and may be broken to
discrete dark parity. The available dark matter candidates in each case
include fermions, scalars, as well as {\it vector gauge bosons}. This work
points to the unity of matter with dark matter, the origin of which is not {\it
ad hoc}.Comment: 12 pages, no figur
Neutron Stars with Baryon Number Violation, Probing Dark Sectors
The neutron lifetime anomaly has been used to motivate the introduction of new physics with hidden-sector particles coupled to baryon number, and on which neutron stars provide powerful constraints. Although the neutron lifetime anomaly may eventually prove to be of mundane origin, we use it as motivation for a broader review of the ways that baryon number violation, be it real or apparent, and dark sectors can intertwine and how neutron star observables, both present and future, can constrain them
