Bertrand Echenard (Caltech) "Probing light dark matter with the LDMX experiment"

September 28, 2017 @ 4:00 pm - 5:00 pm

Elucidating the nature of dark matter is one of the central challenges
in fundamental physics. Dark matter originating as a thermal relic
from the early Universe is arguably one of the most compelling
paradigm, and WIMP searches have been the main focus of past
experimental efforts. Not as extensively explored, the possibility of
light (sub-GeV) thermal dark matter could arise naturally if it is
part of a dark sector neutral under all Standard Model forces. The
“Light Dark Matter eXperiment” (LDMX) proposes to explore light
thermal dark matter using an electron fixed-target missing momentum
approach with a low current, high-repetition beam. The expected
sensitivity would surpassing by orders of magnitude the reach of any
previous or currently envisioned experiment, and decisively test many
sub-GeV thermal dark matter scenarios.
