Selection and processing of calibration samples to measure the particle identification performance of the LHCb experiment in Run 2

EPJ Techniques and Instrumentation

Table 2 Overview of decay modes that are used to select calibration samples

Species	Low momentum	High momentum
e ^±	B⁺→J/ψK⁺ with J/ψ→e⁺e⁻
μ ^±	B⁺→J/ψK⁺ with J/ψ→μ⁺μ⁻	J/ψ→μ⁺μ⁻
π ^±	\(K^{0}_{\mathrm {s}} \rightarrow \pi ^{+}\pi ^{-}\)	D^∗+→D⁰π⁺ with D⁰→K⁻π⁺
K ^±	\(D^{+}_{s} \rightarrow \phi \pi ^{+}\) with ϕ→K⁺K⁻	D^∗+→D⁰π⁺ with D⁰→K⁻π⁺
\(p, \overline {p}\)	Λ⁰→pπ⁻	\(\Lambda ^{0} \rightarrow p\pi ^{-} \, ; \Lambda ^{+}_{c} \rightarrow pK^{-}\pi ^{+}\)

The high momentum samples are primarily selected, while the low momentum samples are included to maximise the kinematic coverage as much as possible
