Towards Catastrophe Theory for Khovanov–Rozansky Homology
We suggest another way to look at observables in cohomological quantum field theory, which are the Khovanov–Rozansky knot invariants. To do that, we briefly summarise our results on jumps in the analytic fo-rm...

Open AccessMeasurement of the muon flux at the SND@LHC experiment
The Scattering and Neutrino Detector at the LHC (SND@LHC) started taking data at the beginning of Run 3 of the LHC. The experiment is designed to perform measurements with neutrinos produced in proton-proton c...

Nuclear Emulsion Detectors for the Muography of Underground Structure of Holy Dormition Pskov-Caves Monastery
The imaging method based on the absorption and scattering of atmospheric muons (muography method) uses the natural flow of muons formed in the interactions of cosmic rays in the atmosphere. The method is at th...

Open AccessOPERA tau neutrino charged current interactions
The OPERA experiment was designed to discover the vτ appearance in a vμ beam, due to neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of a nuclear photographic emul...

Open AccessSensitivity of the SHiP experiment to dark photons decaying to a pair of charged particles
Dark photons are hypothetical massive vector particles that could mix with ordinary photons. The simplest theoretical model is fully characterised by only two parameters: the mass of the dark photon m ...

Open AccessSensitivity of the SHiP experiment to light dark matter
Dark matter is a well-established theoretical addition to the Standard Model supported by many observations in modern astrophysics and cosmology. In this context, the existence of weakly interacting massive pa...

Open AccessFirst observation of a tau neutrino charged current interaction with charm production in the OPERA experiment
An event topology with two secondary vertices compatible with the decay of short-lived particles was found in the analysis of neutrino interactions in the OPERA target. The observed topology is compatible with...

Open AccessMeasurement of the muon flux from 400 GeV/c protons interacting in a thick molybdenum/tungsten target
The SHiP experiment is proposed to search for very weakly interacting particles beyond the Standard Model which are produced in a 400 GeV/c proton beam dump at the CERN SPS. About \(10^{11}\)1011 muons per spill ...

Open AccessSensitivity of the SHiP experiment to Heavy Neutral Leptons
Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These particles can, among other things, explain the origin of neutrino masses, generate the observed...

Open AccessAre Khovanov-Rozansky polynomials consistent with evolution in the space of knots?
R-coloured knot polynomials for m-strand torus knots Torus[m,n] are described by the Rosso-Jones formula, which is an example of evolution in n with Lyapunov exponents, labelled by Young diagrams from R⊗m. This m...
