Recent STAR measurements suggest a difference in the global spin polarization between hyperons and anti-hyperons, especially at relatively low collision beam energy. One possible cause of this is potential presence in-medium magnetic field. In study, we investigate phenomenological viability interpretation. Using AMPT model framework, quantify influence different field evolution scenarios on size wide span energies. We find that such very sensitive to lifetime For same lifetime, computed...

The STAR Collaboration reports on the photoproduction of $\pi^+\pi^-$ pairs in gold-gold collisions at a center-of-mass energy 200 GeV/nucleon-pair. These pion are produced when nearly-real photon emitted by one ion scatters from other ion. We fit invariant mass spectrum with combination $\rho$ and $\omega$ resonances direct continuum. This is first observation ultra-peripheral collisions, measurement $\rho-\omega$ interference energies where dominated Pomeron exchange. amplitude consistent...

In 2017, STAR Collaboration reported the measurements of hyperon global polarization in heavy ion collisions, suggesting subatomic fireball fluid created these collisions as most vortical fluid. There remains interesting question: at which beam energy truly will be located. this work we perform a systematic study on dependence phenomenon, especially $\hat{O}(1\sim 10)\ \rm GeV$ region. We find non-monotonic trend, with to first increase and then decrease when is lowered from $27~\rm down...

Abstract Water is essential for the formation of granites and continental crust, whereas charnockite, being an important component deep inferred to be formed in low‐water environments. Charnockite orthopyroxene‐bearing felsic rock, its origin, generation, preservation remain hotly debated. Quantifying magma water content charnockite further determining orthopyroxene mechanism crucial understanding petrogenesis charnockite. Here, we report a ca. 431 Ma peraluminous Gaozhou with granulitic...

Flow harmonics (vn) in the Fourier expansion of azimuthal distribution particles are widely used to quantify anisotropy particle emission high-energy heavy-ion collisions. The symmetric cumulants, SC(m,n), measure correlations between different orders flow harmonics. These constrain initial conditions and transport properties medium theoretical models. In this Letter, we present first measurements four-particle cumulants Au+Au collisions at sNN=39 200 GeV from data collected by STAR...

Abstract The quality of the surface water along Kunhar River in Mansehra district, KPK Pakistan was assessed for ten samples stations. A variety parameters indicating including physicochemical parameters, nutrients, heavy metals, and antibiotic residues were measured both rainy dry seasons, two main tropical seasons Mansehra, using standard methods. River, one local drinking sources, studied to assess metal content, health risk assessment, its suitability human consumption. Health assessment...

We investigate the periodically modulated two-level systems with balanced gain and loss by means of a multiple-scale asymptotic analysis. The pseudo-parity–time symmetry (2013 Phys. Rev. Lett. 110 243902), which is often neglected in exact numerical simulations totally lost commonly used high-frequency averaging approximation, has been fully understood framework second-order perturbative theory. Our work indicates that expansion method can be to predict precisely some subtle important...

The fractional-order chaotic systems have more complex dynamic characteristics than the integer order systems, which can reflect physical properties of actual system and practical values, whereas it is difficult to control synchronisation for fractional systems.

A complete characterization and quantification of entanglement, particularly the multipartite remains an unfinished long-term goal in quantum information theory. As long as system is concerned, relation between entanglement contained different partitions or subsystems need to take into account. The measure monogamy a framework that just deals with such issue. In this paper, we put forward conditions justify whether monotone (MEM) genuine (GMEM) are complete, completely monogamous, tightly...

Studies of exotic hadrons such as the $\chi_{c1} (3872)$ state provide crucial insights into fundamental force governing strong interaction dynamics, with an emerging new frontier to investigate their production in high energy collisions where a partonic medium is present. Latest experimental measurements from Large Hadron Collider show intriguing evolution pattern (3872)$-to-$\psi(2S)$ yield ratio proton-proton increasing multiplicities toward proton-lead and lead-lead collisions. Here we...

The Marinoan diamictites and the overlying cap carbonates at continental margins bear key information on paleo-environment evolution during collapse of Snowball Earth, such as timespan intense chemical weathering. Such a sedimentary suite has been recently discovered in northwestern Tarim Craton China, but its depositional processes remain controversial. Here, we present stratigraphic isotope geochemical studies Yuermeinak Formation Sugetbrak Aksu region Craton. Multiple unconformities...
