Strong interactions preserve an approximate isospin symmetry between up (u) and down (d) quarks, part of the more general flavor symmetry. In case K meson production, if this were exact, it would result in equal numbers charged (K+ K−) neutral (K0 $${\overline{K}}^{0}$$ ) mesons produced collisions isospin-symmetric atomic nuclei. Here, we report results on relative abundance over production argon scandium nuclei at a center-of-mass energy 11.9 GeV per nucleon pair. We find that K+ K−...
In June 2012, an Expression of Interest for a long-baseline experiment (LBNO) has been submitted to the CERN SPSC. LBNO considers three types neutrino detector technologies: double-phase liquid argon (LAr) TPC and magnetised iron as far detectors. For near detector, high-pressure gas embedded in calorimeter magnet is baseline design. A mandatory milestone concrete prototyping effort towards envisioned large-scale detectors, accompanying campaign measurements aimed at assessing associated...
The most challenging and impactful uncertainties that future accelerator-based measurements of neutrino oscillations must overcome stem from our limited ability to model few-GeV neutrino-nucleus interactions. In particular, it is crucial better understand the nuclear effects which can alter final state topology kinematics interactions, inducing possible biases in energy reconstruction. upgraded ND280 near detector T2K experiment will directly confront interaction using a new suite detectors...
