Description
A long standing problem in kinematics at the hadron colliders is to determine the mass of invisible particles. This issue is particularly important for the signals of dark matter, which becomes one of the prominent targets of future collider experiments. In this paper, we show that the additional information from the precise timing measurement, which will be available at the planned high-liminosity run of the LHC (HL-LHC), will shade new light on the kinematics study. As a concrete example, we focus on the signal of the pair produced long-lived particles (𝐿𝐿𝑃1,2), respectively leaving displaced vertex with visible (𝑉1,2) and invisible (𝐼1,2) final state, 𝑝𝑝→𝐿𝐿𝑃1+𝐿𝐿𝑃2→(𝑉1+𝐼1)+(𝑉2+𝐼2). We explicitly show that this system is completely solvable with timing information.
