“…So we have to rely on theoretical models and utilize ω parton FFs at a starting scale Q 2 0 = 1.5 GeV 2 provided by a broken SU(3) model [39,40]. We note that our preceding investigations on leading ρ 0 and φ production [26,27] have benefited from this broken SU(3) model. In this model, the independent parton FFs of different flavor are reduced into three independent functions named valence function,…”

“…We have achieved a better understanding of the suppression patterns of different mesons by conducting calculations and by analysis of the R AA and particle ratios for other identified hadron productions [25][26][27]. We find that understanding of the suppression pattern of the leading hadron requires one to take into account all three factors [25]: the initial hard jet spectrum, the energy loss mechanism and the parton fragmentation functions in vacuum.…”

“…The flavor dependence of the energy loss will result in a decrease of the fraction of gluon fragmenting contribution in the nuclear-nuclear collision and an increase of the fraction of the quark fragmenting contribution. The productions of final-state mesons, like π 0 , ρ 0 , η [25][26][27], are dominated by the quark fragmentation contribution at the highp T regime in p+p collisions. The energy loss effect will only enhance the domination of the quark fragmenting contribution in A+A collisions.…”

“…The productions of these two mesons have been measured in p+p and A+A collisions both at RHIC and LHC, but a theoretical description is lacking. Within the NLO pQCD improved parton model, we calculate ω and K 0 S yields at the highp T regime in heavy-ion collisions, by employing medium-modification fragmentation functions (FFs) due to gluon radiation in the hot/dense QCD medium in the higher-twist approach of jet quenching [22,23,[28][29][30], the same approach as in our calculations on the productions of η, ρ 0 and φ mesons in HIC [25][26][27].…”

In this work, we pave the way to calculate the productions of ω and K 0 S mesons with large p T in p+p and A+A collisions both at RHIC and LHC. The fragmentation functions (FFs) of the ω meson in vacuum at nextto-leading order (NLO) are obtained by evolving the NLO DGLAP evolution equations with rescaled ω FFs at initial scale Q 2 0 = 1.5 GeV 2 from a broken SU(3) model, and the FFs of K 0 S in vacuum are taken from AKK08 parametrization directly. Within the framework of the NLO pQCD improved parton model, we arrive at good descriptions of the experimental data on ω and K 0 S in p+p both at RHIC and LHC. With the higher-twist approach, to take into account jet quenching effect by medium-modified FFs, nuclear modification factors for ω meson and K 0 S meson both at RHIC and LHC are presented with different sets of jet transport coefficientsq 0. Then we make a global extraction ofq 0 both at RHIC and LHC by confronting our model calculations with all available data on six identified mesons: π 0 , η, ρ 0 , φ, ω, and K 0 S. The minimum value of total χ 2 /d.o. f for productions of these mesons gives the best value ofq 0 = 0.5 GeV 2 /fm for Au+Au collisions with √ s NN = 200 GeV at RHIC, andq 0 = 1.2 GeV 2 /fm for Pb+Pb collisions with √ s NN = 2.76 TeV at LHC, respectively, with the QGP spacetime evolution given by the event-by-event viscous hydrodynamics model IEBE-VISHNU. With these global extracted values ofq 0 , nuclear modification factors of π 0 , η, ρ 0 , φ, ω, and K 0 S in A+A collisions are presented, and predictions of yield ratios such as ω/π 0 and K 0 S /π 0 at the highp T regime in heavy-ion collisions both at RHIC and LHC are provided.

FeSe superconductors and their related systems have attracted much attention in the study of iron-based superconductors owing to their simple crystal structure and peculiar electronic and physical properties. The bulk FeSe superconductor has a superconducting transition temperature (Tc) of ~8 K and it can be dramatically enhanced to 37 K at high pressure. On the other hand, its cousin system, FeTe, possesses a unique antiferromagnetic ground state but is non-superconducting. Substitution of Se with Te in the FeSe superconductor results in an enhancement of Tc up to 14.5 K and superconductivity can persist over a large composition range in the Fe(Se,Te) system. Intercalation of the FeSe superconductor leads to the discovery of the AxFe2-ySe2 (A = K, Cs and Tl) system that exhibits a Tc higher than 30 K and a unique electronic structure of the superconducting phase. A recent report of possible high temperature superconductivity in single-layer FeSe/SrTiO3 films with a Tc above 65 K has generated much excitement in the community. This pioneering work opens a door for interface superconductivity to explore for high Tc superconductors. The distinct electronic structure and superconducting gap, layer-dependent behavior and insulator-superconductor transition of the FeSe/SrTiO3 films provide critical information in understanding the superconductivity mechanism of iron-based superconductors. In this paper, we present a brief review of the investigation of the electronic structure and superconductivity of the FeSe superconductor and related systems, with a particular focus on the FeSe films.

Most epoxy resins (EP) suffer from sacrificial mechanical properties in flame retardancy applications. Through a facile reaction between N‐aminoethylpiperazine (N‐AEP) and 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO), a novel multi‐site interaction flame retardant, DOPO‐based aminoethylpiperazine (abbreviate as AEPO), was successfully synthesized, which could form a ladder‐like cross‐linked network with EP. EP modified by AEPO (EP‐AEPO) was tested for flame retardancy using the limiting oxygen index (LOI), the vertical burning test (UL‐94), and the cone calorimeter test (CCT). According to the results, EP‐10 (EP with 10 phr of AEPO) could pass UL‐94 V‐0 rating and get a LOI value of 35.5%, the peak heat release rate (PHRR) and total heat release (THR) of EP‐10 were also decreased by 25.2% and 29.8%, respectively, which caused by the synergistic charring effect of phosphorus and nitrogen elements contained in the structure of AEPO. Due to the ladder‐like cross‐linked network formed through multi‐site interaction, the mechanical properties demonstrated a significant improved. This work opened up a new strategy for achieving a comprehensive improvement on multifunctional EP through the design of a novel ladder‐like cross‐linked network with multi‐site interaction.
