New Gauge Forces, Neutron Stars and Schwinger Neutrino Production

Yuxin Liu, Zhen Liu, Andrey Shkerin +2

We investigate neutrino effects of new long-range forces arising from gauging $B - L$ , $L_{e} - L_{I^¼/ I ¨ }$ or $L_{I^} ¼ - L_{I ¨} $ symmetries of the Standard Model. The leptonic potential generat…

Constraints on Symmetric Dark Matter from Neutron Star Capture and Collapse

Yuxin Liu, Zhen Liu, Maxim Pospelov +1

Dark matter (DM) models with a conserved particle $-$ antiparticle number, $n_{I ¨} - n_{I ¨ ~ }$ , and the asymmetry in the cosmological abundance $n_{I ¨} \neq = n_{I ¨ ~ }$ , are known t…
