Description
Antimatter in cosmic rays is a powerful probe for Dark Matter indirect de-
tection. To constrain the background from secondary antiparticles, produced
during cosmic ray propagation through the interstellar medium, the related cross
sections need to be precisely determined at accelerator facilities. In particular,
being their secondary production suppressed at low energies with respect to
DM signal predictions, light anti-nuclei like anti-deuterium and anti-helium are
smoking guns for exotic sources. The LHCb experiment currently offers a unique
fixed-target facility exploiting the beam energy provided by LHC and can re-
produce cosmic collisions between protons at the TeV scale and gas targets of
helium. In this poster, we will present the implementation of a new particle identification technique optimized for heavy particles like light nuclei, based on
a time-of-flight measurement in the LHCb Outer Tracker detector, with a fo-
cus on the first performance results obtained on data. Applications in future
analyses will also be discussed
