the pp collision of the LHC, and at the same time (iii) changing the trigger menu to optimize it …

… For displacedjet signatures, ζ tends to be small since the jets are not compatible with
primary vertices. Dijet candidates with ζ larger than 0.2 are rejected. We do not require the …

… In contrast, for background events, vll does not correspond to the flight direction of any
long-lived particle, so its angular distribution with respect to pll should not show any forward-…
