Times Cited Count：8 Percentile：49.7(Physics, Nuclear)Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to collisions.

Times Cited Count：13 Percentile：52.05(Physics, Condensed Matter)We report neutron spin-echo measurements on three types of poly(vinyl alcohol) (PVA) gels. The first is PVA gel in a mixture of dimethyl sulfoxide (DMSO) and water with volume ratio 60/40, the second is PVA gel in an aqueous borax solution and the third is chemically cross-linked PVA gel. The observed normalized intermediate scattering functions I(Q,t)/I(Q,0) were very different among them. The I(Q,t)/I(Q,0) of the first and third gels showed a non-decaying component in addition to a decaying component, but the second one did not have the non-decaying one. This clearly indicates that the fluctuations in the first and third PVA gels consist of static and dynamic fluctuations whereas the second PVA gel does include only the dynamic fluctuations. The dynamic and static fluctuations of the PVA gels were analyzed in terms of a restricted motion in the gel network and the Zimm motion, respectively.

We have extensively studied nano-scale structure and dynamics of three types of poly(vinyl alcohol) (PVA) gels by using small-angle neutron scattering (SANS) and neutron spin-echo (NSE) techniques; two physical gels and one chemical gel. The first one was a PVA gel in a mixture of deuterated dimethyl sulfoxide (DMSO-d6) and D2O with volume fraction of DMSO-d6 being 0.6, in which cross-links were made of crystallites. On the basis of NSE results, SANS intensity was divided into static and dynamic fluctuations to find that the former contribution was dominant in the present wave vector (Q) range. The latter, dynamic fluctuations were analyzed in terms of fluctuations of cross-links in the quasi-equilibrium position. The second gel was PVA in aqueous borax solution. The intermediate scattering functions of the gel as well as the sol were well described by Zimm mode and gel mode in Q regions of above and below a critical wave vector (Qc). The last one was the chemically cross-linked PVA gel. The intermediate scattering function was also described by Zimm mode in a short-time region, suggesting that it behaves like polymer solution. However, in a long-time region, the data points deviated from Zimm-scaled master curve, suggesting that it was restricted by the cross-links made of covalent bonds.
