Investigation on Moisture and Salt Transport in Heterogeneous Porous Media of Relics-Soil in Archaeology Museum

The unearthed relics in archaeology museum are usually being presented to the public as still partly connected to their primitive environment. Migration of moisture may cause the carbonate from the soil being deposited on the relic’s surface and some carbonates would react with the penetrating SO2 to form sulphates, which will change the relics’ primitive form and material properties. In this research, experiments were carried out to clarify the migration mechanism of water and salt in a soil-relic-atmosphere coupling environment. The research results show that there existing a one-way transport of moisture from the soil-relics to the air even though the relative humidity approximates to 100%. Meanwhile, the effects of soil properties, air temperature, relative humidity and salt concentration on the transports of moisture and salt are identified

Evidence for the singly Cabibbo suppressed decay Lambda_c+ --> p eta and search for Lambda_c+ --> p pi0

We study the singly Cabibbo suppressed decays Lambda_c+ --> p eta and Lambda_c+ → pπ0 using Lambda+Lambda_c- pairs produced by e+e- collisions at a center-of-mass energy of sqrt(s) =4.6 GeV. The data sample was collected by the BESIII detector at the BEPCII collider and corresponds to an integrated luminosity of 567 pb-1. We find the first evidence for the decay Lambda_c+ --> p eta with a statistical significance of 4.2 sigma and measure its branching fraction to be B( Lambda_c+ --> p eta)=(1.24±0.28(stat)±0.10(syst))10-3. No significant Lambda_c+ --> p pi0 signal is observed. We set an upper limit on its branching fraction B( Lambda_c+ --> p pi0)<2.7x10-4 at the 90% confidence level

Measurements of cross section of e+e- --> ppbar pi0 at center-of-mass energies between 4.008 and 4.600 GeV

Based on e+e- annihilation data samples collected with the BESIII detector at the BEPCII collider at 13 center-of-mass energies from 4.008 to 4.600 GeV, measurements of the Born cross section of e+e- --> ppbar pi0 are performed. No significant resonant structure is observed in the measured energy dependence of the cross section. The upper limit on the Born cross section of e+e- --> Y(4260) --> ppbar pi0 at the 90% C.L. is determined to be 0.01 pb. The upper limit on the ratio of the branching fractions B(Y(4260) --> ppbar pi0 )/ B(Y(4260) --> pi+pi-Jpsi) at the 90% C.L. is determined to be 0.02%

Precise Measurement of the e+e- →π+π-J /ψ Cross Section at Center-of-Mass Energies from 3.77 to 4.60 GeV

The cross section for the process e+e-→π+π-J/ψ is measured precisely at center-of-mass energies from 3.77 to 4.60 GeV using 9 fb-1 of data collected with the BESIII detector operating at the BEPCII storage ring. Two resonant structures are observed in a fit to the cross section. The first resonance has a mass of (4222.0±3.1±1.4) MeV/c2 and a width of (44.1±4.3±2.0) MeV, while the second one has a mass of (4320.0±10.4±7.0) MeV/c2 and a width of (101.4-19.7+25.3±10.2) MeV, where the first errors are statistical and second ones are systematic. The first resonance agrees with the Y(4260) resonance reported by previous experiments. The precision of its resonant parameters is improved significantly. The second resonance is observed in e+e-→π+π-J/ψ for the first time. The statistical significance of this resonance is estimated to be larger than 7.6σ. The mass and width of the second resonance agree with the Y(4360) resonance reported by the BABAR and Belle experiments within errors. Finally, the Y(4008) resonance previously observed by the Belle experiment is not confirmed in the description of the BESIII data

Measurement of cross sections of the interactions e + e − → ϕϕω and e + e − → ϕϕϕ at center-of-mass energies from 4.008 to 4.600 GeV

Using data samples collected with the BESIII detector at the BEPCII collider at six center-of-mass energies between 4.008 and 4.600 GeV, we observe the processes e+e− → φφω and e+e− → φφφ. The Born cross sections are measured and the ratio of the cross sections σ (e+e− → φφω)/σ (e+e− → φφφ) is estimated to be 1.75±0.22±0.19 averaged over six energy points, where the first uncertainty is statistical and the second is systematic. The results represent first measurements of these interactions
