Kinetics of order-disorder transitions including melting in low-dimensional systems is theoretically predicted to be heterogeneous that start by nucleation in defect sites at lower than homogeneous bulk-melting temperature requiring substantially lower energy barrier. We probed kinetics of such transition in thin multilayered films using x-ray scattering and in situ atomic force microscopy (AFM) studies. [...]

A search is performed for light, spin-0 bosons decaying into two photons in the 66 to 110 GeV mass range, using 140 fb$^{−1}$ of proton-proton collisions at $ \sqrt{s} $ = 13 TeV produced by the Large Hadron Collider and collected by the ATLAS detector. Multivariate analysis techniques are used to define event categories that improve the sensitivity to new resonances beyond the Standard Model [...]

We report a study of the inelasticity distribution in the scattering of neutrinos of energy 80–560 GeV off nucleons. Using atmospheric muon neutrinos detected in IceCube’s sub-array DeepCore during 2012–2021, we fit the observed inelasticity in the data to a parameterized expectation and extract the values that describe it best.
