We review in this contribution the information we can obtain from heavy-ion experiments about the interaction of mesons with matter. We demonstrate that the vector mesons seen in experiments come predominantly from low densities. Kaons offer a better opportunity but most of the presently available experimental observables do not allow to analyze separately the three essential unknown quantities: the kaon production cross-section in the medium, the K+N potential interaction at finite densities and temperatures and the kaon (elastic or charge exchange) rescattering cross-section in the medium. We propose a measurement which almost exclusively tests the K+N potential.

Modification Factor

The Large Hadron Collider at CERN allows us to study heavy-ion collisions at an un- precedented energy. ALICE, A Large Ion Collider Experiment, is the experiment ded- icated to the investigation of heavy-ion collisions. In this contribution, recent open heavy-flavour results from pp collisions at [Formula: see text]= 5.02, 7, 8 and 13 TeV and p–Pb collisions at [Formula: see text] = 5.02 TeV, collected with the ALICE detector during the LHC Run-1 and Run-2 are presented. The results include the production cross section, nuclear modification factor and multiplicity dependence studies of production of D mesons and electrons from heavy-flavour hadron decays at mid-rapidity and of muons from heavy-flavour hadron decays at forward rapidity. Charm production was measured down to [Formula: see text] = 0 GeV/[Formula: see text] in pp and p–Pb collisions. Recent measurements of the production cross section of heavy charmed baryons such as [Formula: see text] (in pp and p–Pb) and [Formula: see text] (in pp) are discussed. The results are compared with theoretical model predictions.

Abstract 3D TCAD simulations demonstrated that reducing the distance between the well boundary and NMOS or PMOS can mitigate the cross section of Single Event Upset (SEU) in 14 nm CMOS bulk FinFET technology. The competition of charge collection between well boundary and sensitive nodes, the enhanced restore currents and the change of bipolar effect are responsible for the decrease of SEU cross section. Different from Dual-interlock cells (DICE) design, under the presence of enough taps to ensure the rapid recovery of well potential, this approach is more effective under heavy ion irradiation of higher LET. Besides, the feasibility of this method and its effectiveness with feature size scaling down are discussed.

Gluon Production

We study two-particle long-range rapidity correlations arising in the early stages of heavy ion collisions in the saturation/Color Glass Condensate framework, assuming for simplicity that one colliding nucleus is much larger than the other. We calculate the two-gluon production cross section while including all-order saturation effects in the heavy nucleus with the lowest-order rescattering in the lighter nucleus. We find four types of correlations in the two-gluon production cross section: (i) geometric correlations, (ii) HBT correlations accompanied by a back-to-back maximum, (iii) away-side correlations, and (iv) near-side azimuthal correlations which are long-range in rapidity. The geometric correlations (i) are due to the fact that nucleons are correlated by simply being confined within the same nucleus and may lead to long-range rapidity correlations for the produced particles without strong azimuthal angle dependence. Somewhat surprisingly, long-range rapidity correlations (iii) and (iv) have exactly the same amplitudes along with azimuthal and rapidity shapes: one centered around Δϕ = π with the other one centered around Δϕ = 0 (here Δϕ is the azimuthal angle between the two produced gluons). We thus observe that the early-time CGC dynamics in nucleus-nucleus collisions generates azimuthal non-flow correlations which are qualitatively different from jet correlations by being long-range in rapidity. If strong enough, they have the potential of mimicking the elliptic (and higher-order even-harmonic) flow in the di-hadron correlators: one may need to take them into account in the experimental determination of the flow observables.
