Abstract
Abstract
We show that the NANOGrav signal can come from the Higgs
field with a noncanonical kinetic term in terms of the scalar
induced gravitational waves. The scalar induced gravitational waves
generated in our model are also detectable by space-based
gravitational wave observatories. Primordial black holes with
stellar masses that can explain LIGO-Virgo events are also produced.
Therefore, the NANOGrav signal and the BHs in LIGO-Virgo events may
both originate from the Higgs field.
