 “Light majoron cold dark matter from topological defects and the formation of boson stars”
Mario Reig
(IFIC Valencia)

In this seminar I will show that for a relatively light majoron ( << 100 eV) non-thermal production from topological defects

is an efficient production mechanism. Taking the type I seesaw as benchmark scheme, I will estimate the primordial majoron

abundance and determine the required parameter choices where it can account for the observed cosmological dark matter.

Possible direct detection of light majorons with future experiments such as PTOLEMY and the formation of boson stars from

the majoron dark matter will be also discussed.
