<jats:title>Abstract</jats:title> <jats:p>The sensitivity of the direct detection of dark matter (DM) approaches the so-called neutrino floor, below which it is difficult to disentangle the DM candidate from the neutrino background. In this work, we consider the scenario that no DM signals are reported in various DM direct detection experiments and explore whether collider searches could probe DM below the neutrino floor. We adopt several simplified models in which the DM candidate couples to electroweak gauge bosons or leptons in the standard model only through high-dimensional operators. After including the RGE running effect, we investigate the constraints of direct detection, indirect detection, and collider searches. The collider search can probe light DM below the neutrino floor. Particularly, for the effective interaction of <jats:inline-formula> <jats:tex-math><?CDATA $ \bar{\chi}\chi B_{\mu\nu}B^{\mu\nu}$?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="cpc_44_11_113105_Mi.jpg" xlink:type="simple" /> </jats:inline-formula>, current data from the mono-photon channel at the 13 TeV LHC has already covered the entire parameter space of the neutrino floor. </jats:p>

<jats:title>Abstract</jats:title> <jats:p>Within an advanced Langevin-hydrodynamics framework coupled to a hybrid fragmentation-coalescence hadronization model, we study heavy flavor quenching and flow in relativistic heavy-ion collisions. We investigate how the initial heavy quark spectrum, the in-medium energy loss and hadronization mechanisms of heavy quarks, the evolution profile of the pre-equilibrium stage, the medium flow, and the temperature dependence of heavy quark diffusion coefficients influence the suppression and elliptic flow of heavy mesons at the RHIC and the LHC. Our results show that the different modeling of initial conditions, pre-equilibrium evolution, and in-medium interactions can individually yield uncertainties of approximately 10-40% in <jats:italic>D</jats:italic> meson suppression and flow at a low transverse momentum. We also find that proper combinations of collisional versus radiative energy loss, coalescence versus fragmentation in hadronization, and the inclusion of medium flow are the most important factors for describing the suppression and elliptic flow of heavy mesons. </jats:p>

A gridded twin ionization chamber (GIC) was used as the detector, and enriched <jats:sup>58</jats:sup>Ni, <jats:sup>60</jats:sup>Ni, and <jats:sup>61</jats:sup>Ni foil samples were prepared and mounted at the sample changer of the GIC. Three highly enriched <jats:sup>238</jats:sup>U<jats:sub>3</jats:sub>O<jats:sub>8</jats:sub> samples inside the GIC were used to determine the relative and absolute neutron fluxes. The neutron energy spectra were obtained through unfolding the pulse height spectra measured by the EJ-309 liquid scintillator. The interference from the low-energy neutrons and impurities in the samples has been corrected. The present data of the <jats:sup>60</jats:sup>Ni(<jats:italic>n</jats:italic>, <jats:italic>α</jats:italic>)<jats:sup>57</jats:sup>Fe reaction are the first measurement results below 6.0 MeV, and those of the <jats:sup>61</jats:sup>Ni(<jats:italic>n</jats:italic>, <jats:italic>α</jats:italic>)<jats:sup>58</jats:sup>Fe reactions are the first measurement results in the MeV region.

<jats:title>Abstract</jats:title> <jats:p>Proton-induced scattering of <jats:sup>238</jats:sup>U nuclei, with spheroidal deformations at beam energies above 100 MeV, is simulated using an improved quantum molecular dynamics model. The angular distribution of the deflected protons is highly sensitive to the orientation of the symmetrical long axis of the target nuclei with respect to the beam direction. As a result, in reverse kinematic reactions, an orientation dichroism effect is predicted, implying that the absorption rate of the <jats:sup>238</jats:sup>U beam by a proton target discerns between the parallel and perpendicular orientations of the deformed <jats:sup>238</jats:sup>U nuclei. </jats:p>
