Abstract We re-analyze published proton beam dump data taken at the U70 accelerator at IHEP Serpukhov with the ν-calorimeter I experiment in 1989 to set mass-coupling limits for dark gauge forces. The corresponding data have been used for axion and light Higgs particle searches in Blumlein et al. (1991, 1992) [1] , [2] before. We determine new mass and coupling exclusion bounds for dark gauge bosons.

ALPtraum: ALP production in proton beam dump experiments (2015, methodology): “The two most constraining experiments are9 CHARM [12], which has recently been used to derive constraints on light scalars and pseudoscalars with couplings to quarks [33, 34], and NuCal [5], which has been reanalysed for the case of hidden photons [23, 24].”
Serendipity in dark photon searches (2018, unknown): “2 Proton beam dumps Limits on A′ → e+e− decays have been set by the following experiments: ν-CAL I [119, 120], using π0 → A′γ decays [20] and proton bremsstrahlung [22]; CHARM [121], using η(′) → A′γ decays [21]; and NOMAD [17] and PS191 [33] using π0 → A′γ decays [36].”
A taste of dark matter: flavour constraints on pseudoscalar mediators (2014, unknown): “We have calculated the constraints from CHARM, following [72, 105] and estimated the implications of NuCal, following [106, 107].”
Revisiting Supernova 1987A constraints on dark photons (2016, methodology): “Above 2me, bounds from beam-dumps, B- and Φ-factories, fixed-target experiments, and precision measurements of the muon and electron (“ae”) anomalous magnetic moment are applicable [4, 12, 52–70].”
Dark Matter's secret liaisons: phenomenology of a dark U(1) sector with bound states (2016, methodology): “Among them, the reinterpretation of Lsnd [105–107], Charm [108, 109] and ν-Cal I (at the U70 accelerator) [110, 111] data allows to exclude the gray shaded areas in fig.”
Particle physics models for the 17 MeV anomaly in beryllium nuclear decays (2016, background): “The ν-Cal I experiment at the U70 accelerator at IHEP sets bounds from X-bremsstrahlung off the initial proton beam [61] and π → Xγ decays [62].”
