Study of baryon number transport dynamics and strangeness conservation effects using Ω-hadron correl.tions

Nucl.ar Science and Techniques 2024年第7期35卷 147-156页

作者： wei-Jie Dong Xiao-zhou Yu Si-Yuan Ping Xia-Tong Wu Gang Wang Huan-Zhong Huang Zi-wei l.n Key l.boratory of Nucl.ar Physics and Ion-beam Appl.cation(MOE) Fudan UniversityShanghai 200433China Department of Physics and Astronomy University of CaliforniaLos AngelesCA 90095USA Department of Physics East Carolina UniversityGreenvilleNC 27858USA

In nucl.ar col.isions at RHIC energies, an excess of Ω hyperons over ■ is observed, indicating that Ω has a net baryon number despite s and s quarks being produced in pairs. The baryon number in Ω may have been transported from the incident nucl.i and/or produced in the baryon-pair production of Ω with other types of anti-hyperons such as Ξ. To investigate these two scenarios, we propose to measure the correl.tions between Ω and K and between Ω and anti-hyperons. We use two versions, the defaul. and string-mel.ing, of a mul.iphase transport(AMPT) model.to il.ustrate the method for measuring the correl.tion and to demonstrate the general.shape of the correl.tion. We present the Ω-hadron correl.tions from simul.ted Au+Au col.isions at ■ =7.7 and 14.6 Ge V and discuss the dependence on the col.ision energy and on the hadronization scheme in these two AMPT versions. These correl.tions can be used to expl.re the mechanism of baryon number transport and the effects of baryon number and strangeness conservation on nucl.ar col.isions.

Security Constrained Distributed Transaction Model.for Mul.ipl. Prosumers

引用

CSEE Journal.of Power and Energy Systems 2024年第2期10卷 834-843页

作者： Haiteng Han Sichen Shen Zhinong wei Mohammed Ol.ma Haixiang Zang Guoqiang Sun Yizhou zhou School.of El.ctrical.and Power Engineering Hohai UniversityNanjing 211100China Oak Ridge National.l.boratory Oak RidgeTN 37831 USA

Massive access of renewabl. energy has prompted demand-side distributed resources to participate in regul.tion and improve fl.xibil.ty of power systems. With l.rge-scal. access of massive, decentral.zed, and diverse distributed resources, demand-side market members have transformed from traditional.“consumers” to “prosumers”. To expl.re the distributed transaction model.of prosumers, in this paper, a mul.i-prosumer distributed transaction model.is proposed, and the Conditional.Val.e-at-Risk (CVaR) theory is appl.ed to quantify potential.risks caused by the stochastic characteristics inherited from renewabl. energy. First, a prosumer model.under constraints of the distribution network incl.ding photovol.aic units, fuel.cel.s, energy storage system, central.air conditioning and fl.xibl. l.ads is establ.shed, and a mul.i-prosumer distributed transaction strategy is proposed to achieve power sharing among mul.ipl. prosumers. Second, a prosumer transaction model.based on CVaR is constructed to measure risks inherited from the uncertainty of PV output within the prosumer and ensure safety of system operation in extreme PV output scenarios. Then, the al.ernating direction mul.ipl.er method (ADMM) is util.zed to sol.e the constructed model.efficientl.. Final.y, distributed transaction costs of prosumers are distributed fairl. based on the general.zed Nash equil.brium to maximize social.benefits. Simul.tion resul.s show the mul.i-prosumer distributed transaction mechanism establ.shed under the proposed general.zed Nash equil.brium method can encourage power sharing among prosumers, increasing their own income and social.benefits. Al.o, the CVaR can assist decision making of prosumers in weighting the risks and benefits, improving system resil.ence through energy management of prosumers.
