A new general purpose fixed target facility is proposed at the CERN SPS accelerator which aimed exploring domain of hidden particles and make measurements with tau neutrinos. Hidden are predicted by a large number models beyond Standard Model. The high intensity 400~GeV beam allows probing wide variety containing light long-lived exotic masses below ${\cal O}$(10)~GeV/c$^2$, including very weakly interacting low-energy SUSY states. experimental programme capable being extended in future,...
Very intense neutrino beams and large detectors will be needed in order to enable the discovery of CP violation leptonic sector. We propose use proton linac European Spallation Source currently under construction Lund, Sweden deliver, parallel with spallation neutron production, a very intense, cost effective high performance beam. The baseline program for is that it fully operational at 5 MW average power by 2022, producing 2 GeV 2.86 ms long pulses rate 14 Hz. Our proposal upgrade 10 28...

In the effort to obtain a precise measurement of leptonic CP-violation with ESS$\nu$SB experiment, accurate and fast reconstruction detector events plays pivotal role. this work, we examine possibility replacing currently proposed likelihood-based method an approach based on Graph Neural Networks (GNNs). As is reasonably but computationally expensive, one benefits Machine Learning (ML) enabling event in development phase, allowing for easier investigation effects changes design. Focusing...
The nuclear emulsion target of the CHORUS detector was exposed to wide-band neutrino beam CERN SPS 27 GeV average energy from 1994 1997. In total, about 100 000 charged-current (CC) interactions with at least one identified muon were located in and fully reconstructed, using newly developed automated scanning systems. Charmed particles searched for by a program recognizing particle decays. observation decay makes it possible select sample very low background minimal kinematical bias. all,...

We have studied the reaction $p+$$^{27}\mathrm{Al}$ $\ensuremath{\rightarrow}$ $^{3}\mathrm{He}$$+p+{\ensuremath{\pi}}^{\ensuremath{-}}+X$ at recoil-free kinematics. An $\ensuremath{\eta}$ meson possibly produced in this would be thus almost rest laboratory system and could therefore bound with high probability, if nuclear states exist. The decay of such a state through ${N}^{*}(1535)$ resonance lead to proton-${\ensuremath{\pi}}^{\ensuremath{-}}$ pair emitted opposite directions. For these...
A bstract Neutrino oscillation experiments provide a unique window in exploring several new physics scenarios beyond the standard three flavour. One such scenario is quantum decoherence neutrino which tends to destroy interference pattern of neutrinos reaching far detector from source. In this work, we study context ESSnuSB experiment. We consider energy-independent parameter and derive analytical expressions for P μe μμ probabilities vacuum. have computed capability put bounds on parameters...
