Search for a Non-Relativistic Boson in Two-Body Antimuon Decay

J. I. Collar, P. S. Cooper, C. M. Lewis

We demonstrate the feasibility of probing the charged lepton flavor violating decay $μ^{+} \to e^{+} X^{0}$ for the presence of a slow-moving neutral boson $X^{0}$ cap…

Search for inelastic dark matter-nucleus scattering with the PICO-60 CF $_{3}$ I and C $_{3}$ F $_{8}$ bubble chambers

E. Adams, B. Ali, I. J. Arnquist +52

PICO bubble chambers have exceptional sensitivity to inelastic dark matter-nucleus interactions due to a combination of their extended nuclear recoil energy detection window from a…

A measurement of the $K^{+} \to π^{+} μ^{+} μ^{-}$ decay

NA62 Collaboration

A sample of $2.8 \times 1 0^{4}$ $K^{+} \to π^{+} μ^{+} μ^{-}$ candidates with negligible background was collected by the NA62 experiment at the CERN SPS in 2017--2018. The model-inde…

Results on photon-mediated dark matter-nucleus interactions from the PICO-60 C $_{3}$ F $_{8}$ bubble chamber

B. Ali, I. J. Arnquist, D. Baxter +52

Many compelling models predict dark matter coupling to the electromagnetic current through higher multipole interactions, while remaining electrically neutral. Different multipole…

Measurement of the very rare $K^{+} \to π^{+} ν ν ˉ$ decay

NA62 Collaboration

The NA62 experiment reports the branching ratio measurement BR $(K^{+} \to π^{+} ν ν ˉ) = (10. 6_{- 3.4}^{+ 4.0} ∣_{stat} \pm 0. 9_{syst}) \times 1 0^{- 11}$ at 68% CL, base…

Search for heavy neutral lepton production in $K^{+}$ decays to positrons

NA62 collaboration

A search for heavy neutral lepton ( $N$ ) production in $K^{+} \to e^{+} N$ decays using the data sample collected by the NA62 experiment at CERN in 2017--2018 is reported. Upper limits of…
