DESCRIPTION:The increasingly precise neutrino experiments raise the hope f
 or searching for new physics through studying the impact of Neutral Curren
 t (NC) Non-Standard Interactions (NSI) of neutrinos with matter fields. Ne
 utrino oscillation experiments\, along with the Elastic Coherent ν Nucleu
 s Scattering (CENS) experiments\, already set strong bounds on all the fla
 vor elements of the vector NC NSI. However\, axial NC NSI can hide from th
 ese experiments. In our recent study\, https://arxiv.org/abs/2509.02711\,
  we show that the neutral current data of the MINOS and MINOS+ experiments
  can provide information on the axial neutral current non-standard interac
 tions of neutrinos with the $u$ and $d$ quarks\; {\\it i.e.\,} on $\\epsil
 on_{\\alpha \\beta}^{Aq}$. We derive bounds on the $ee$\, $e\\tau$ and $\\
 tau \\tau$ components of these couplings and show that the MINOS(+) bounds
  on $\\epsilon^{Aq}_{e\\tau}$ and $\\epsilon^{Aq}_{\\tau\\tau}$ are curren
 tly the world leading ones. The bound on the isospin singlet case\, $\\eps
 ilon^{Au}_{\\tau\\tau}=\\epsilon^{Ad}_{\\tau\\tau}$\, is of particular int
 erest because while this isospin singlet NSI is theoretically motivated\, 
 it was practically unconstrained before these results.\n\nhttps://indico.i
