“…The pairs produced in heavy ion collisions can have final-state interactions before bound quarkonia could be formed. We found [256] that with both initial-and final-state double scattering, the broadening of heavy quarkonia is close to 2C A /C F times the Drell-Yan broadening in proton-nucleus collision, which is consistent with existing data [257]. If all soft gluons of heavy ion beams are stopped to form the hot dense medium in nucleus-nucleus collisions, final-state interaction between the almost stationary medium and the fast moving heavy quarks (or quarkonia) of transverse momentum q T is unlikely to broaden the q T spectrum, instead, it is likely to slow down the heavy quarks (or quarkonia) [256].…”

“…Particle transverse momentum broadening is the type of observable most directly relevant to q for CNM [74,75]. Our previous global analysis [32] takes into account the current world data on the transverse momentum broadening of single hadron production in SIDIS [6] of eA collisions, of Drell-Yan di-lepton production in pA collisions [76,77], and of heavy quarkonium (J/ψ and Υ) production in pA collisions [7,8,[77][78][79][80]. These observables involve multiple scatterings undergone by quark or gluon jets in the initial or (and) final states of the hard processes, providing multi-dimensional insight into the transport coefficient as well as a place to examine the theoretical framework.…”

We present a study of the nuclear-medium induced transverse momentum broadening of particle production in future electron-ion-collision (EIC) experiments. By considering the multiple scattering between hard partons and cold nuclear medium within the higher-twist factorization framework in perturbative QCD, we calculate the transverse momentum broadening of single hadron production in semi-inclusive measurements, as well as the nuclear enhancement of the transverse momentum imbalance for di-hadron and heavy-meson pair productions. In particular, a kinematics dependent non-perturbative jet transport coefficient q = q(x, Q 2 ) extracted in a global analysis of the current data, together with its uncertainty determined with a Hessian method, are input into our calculations and are available for the community. Significant kinematic and color-state dependences of the nuclear induced broadening/imbalance are predicted. Our results indicate that the future EIC measurements are able to provide powerful constraints on the kinematic dependence of the transport coefficient q and thus greatly facilitate the jet tomography of cold nuclear medium.

“…This is because rutile has a much lower closure temperature (~500°C) than zircon (~900°C) and the U-Pb system of RMJG rutile was reset by later thermal events. Mafic dyke swarms with an age range of 1730-1780 Ma occur in the study area (Peng et al 2008, Peng 2015, Li et al 2015b. Therefore, it is likely that these dyke swarms were emplaced into shallow crust and heated the rutiles.…”

Matrix‐matched reference materials are necessary for accurate microbeam U‐Pb dating and Hf isotopic determination. This study introduces the RMJG rutile as a new potential reference material, which was separated from Palaeoproterozoic pelitic granulites collected in Hebei Province, China. LA‐ICP‐MS measurements indicate the RMJG rutile has extremely low Th (< 0.003 ± 0.01 µg g−1) and common Pb contents, but high Hf (102 ± 34 µg g−1), U (61 ± 11 µg g−1), and radiogenic Pb (~ 20 µg g−1) contents. Moreover, the rutile yields relatively constant U‐Pb ages and Hf isotopic data. The LA‐ICP‐MS analyses suggest that this rutile has a concordant U‐Pb age with a statistical mean 206Pb/238U and 207Pb/235U ages of 1749.9 ± 32.1 Ma and 1750.0 ± 26.4 Ma, respectively (2s), which are statistically indistinguishable from its ID‐TIMS ages (1750.6 ± 8.4 and 1750.1 ± 4.7 Ma). Precise determination of the 176Hf/177Hf ratio by MC‐ICP‐MS in solution mode (0.281652 ± 0.000006) is in good agreement with the statistical mean of the LA‐MC‐ICP‐MS measurements (0.28166 ± 0.00018). Therefore, the limited variations of RMJG U‐Pb age and Hf isotopic composition together with its extremely low common Pb and high Hf, U and Pb contents make it an ideal calibration and monitor reference material for LA‐ICP‐MS measurements.
