Oscillating Imprints of Dark Matter in Mesons Decays
Prisco Lo Chiatto, Babette Döbrich, Gilad Perez
We study scenarios in which ultralight dark matter (ULDM) causes oscillations of the Cabibbo--Kobayashi--Maskawa (CKM) matrix elements, considering two frameworks. The first, previ…

Lorentz violating backgrounds from quadratic, shift-symmetric, ultralight dark matter
Minyuan Jiang, Benjamin D. Pecjak, Gilad Perez +1
We consider an effective theory for a shift-symmetric, quadratically-coupled, ultralight spin-0 field. The leading CP-conserving interactions with Standard Model fields in the effe…

A Note on the Quality of Dilatonic Ultralight Dark Matter
Jay Hubisz, Shaked Ironi, Gilad Perez +1
Dilatons are pseudo-Nambu-Goldstone bosons arising from the breaking of conformal invariance. In this letter we point out that in general a dilaton mass has a power-law dependence…
