Within the framework of nonrelativistic-QCD factorization,we calculate both the next-to-leading-order relativistic and QCD corrections to prompt J/ψpair production,with feed-down fromψ(2S)mesons,via photon-photon collisions at future e^(+)e^(−)colliders,including the Future Circular Lepton Collider(FCC-ee),the Circular Electron Positron Collider(CEPC),and the Compact Linear Collider(CLIC).We present total cross sections and distributions in single J/ψtransverse momentum and rapidity,as well as in J/ψpair invariant *** relativistic and QCD corrections both turn out to be large and ***,the production rates are large enough for useful experimental studies.

Granite-related W-Sn ore systems are commonly associated with coeval Pb-Zn mineralization. It remains unclear whether these metals are derived from the same sources or not. Mercury（Hg） is a common minor component in such systems. Hg isotopes undergo unique mass-independent fractionation(expressed as Δ199Hg values), which is mainly generated during Hg photochemical reactions on Earth's surface and not affected by magmatic-hydrothermal processes, offering an excellent opportunity to trace metal sources in hydrothermal systems. We observed near-zero Δ199Hg values in wolframite（-0.10‰ to0.08‰, n=11）, and in skarn-（-0.17‰ to 0.12‰, n=48） and greisen-type（-0.12‰ to 0.10‰, n=11） bulk tin-tungsten ore from eight major ore deposits in South China. These values are identical to those of coeval highly evolved granites（-0.13‰ to 0.12‰,n=49）, supporting that Hg in W-Sn ores were sourced from granite. However, sulfides（e.g., pyrite, chalcopyrite, arsenopyrite,galena, and sphalerite） in these deposits exhibit negative to near-zero Δ199Hg values（-0.42‰ to 0.09‰, n=124）, which indicates a contribution of Hg and by inference other metals from both Precambrian basement rocks(Δ199Hg<0) and ore-related *** study demonstrates that multiple sources of metals were involved in the formation of the polymetallic W-Sn deposits, and further highlights that extraction of metals from basement rocks may be a critical control on the formation of economically important mineralization of base metal sulfides（e.g., Pb, Zn） in granite-related magmatic-hydrothermal systems.

花岗岩有关的钨锡矿床经常伴随有同时代的铅锌矿化.目前学术界关于该成矿系统中金属的来源尚存在较大争议.汞（Hg）是该成矿系统中常见的伴生组分,它的非质量分馏(表示为Δ199Hg)主要与地球表生环境下的光化学还原反应有关,不受岩浆和热液过程的影响,为示踪岩浆热液体系中成矿金属的来源提供了契机.本文对中国华南地区8个大型-超大型W-Sn多金属矿床开展了汞同位素研究,发现黑钨矿（-0.10‰～0.08‰, n=11）、矽卡岩型钨锡矿石（-0.17‰～0.12‰, n=48）和云英岩型钨锡矿石（-0.12～0.10‰, n=11）均具有近零的Δ199Hg组成,与该地区发育的同时代高分异花岗岩（-0.13‰～0.12‰, n=49）具有一致的同位素组成,表明W-Sn矿石中的Hg主要来自成矿的高分异花岗岩.然而,这些矿床中的硫化物（如黄铁矿、黄铜矿、毒砂、方铅矿和闪锌矿）具有大的Δ199Hg变化范围,从-0.42‰变化至0.09‰,指示硫化物中的Hg、Pb和Zn等成矿金属来自区内前寒武系基底岩石(Δ199Hg<0)和花岗岩的混合.该项研究表明,多种来源的金属参与了花岗岩有关W-Sn多金属成矿系统的演化过程,热液流体从基底岩石中萃取和活化Pb、Zn等成矿物质可能对该成矿系统中贱金属硫化物的成矿起到了关键作用.
