Calculation of phase diagram and the thermodynamic quantities by the Landau mean field model close to the solid  liquid and solid  solid transitions in nparaffins
Yurtseven, Hamit; Tari, Ozlem
We calculate the phase diagrams and predict the temperature dependence of the thermodynamic quantities at high pressures for the solid  liquid and solid  solid transitions in nparaffins. This calculation is performed by fitting the phase line equations as obtainedfrom the Landau model to the experimental data from the literature. On thebasis of the Landau model, phase diagram of the solid  solid transition ispredicted at 0.1 MPa for the binary mixtures of ntridecane + (nhexane and cyclohexane).For the calculation of the heat capacity the extended mean field is employedfor the nparaffins studied here. We find that our calculated phase diagrams explain the observed behaviour of the liquid  solid transitions at high pressures in those binary mixtures. Our phase diagrams predicted at 0.1 MPa and our predictions for the thermodynamic quantities can be compared with the experiments for those binary mixtures.

Using a data set corresponding to an integrated luminosity of 6.32 fb−1 recorded by the BESIII detector at centerofmass energies between 4.178 and 4.226 GeV, an amplitude analysis of the decay Ds+ → π+π0π0 is performed, and the relative fractions and phases of different intermediate processes are determined. The absolute branching fraction of the decay Ds+ → π+π0π0 is measured to be (0.50 ± 0.04stat ± 0.02syst)%. The absolute branching fraction of the intermediate process Ds+ → f0(980)π+, f0(980) → π0π0 is determined to be (0.28 ± 0.04stat ± 0.04syst)%.

Kolcu, Onur Buğra; BESIII Collaboration
Using 6.32 fb−1 of e+e− collision data collected at the centerofmass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysis of the decay Ds+→ K+π+π− and determine the amplitudes of the various intermediate states. The absolute branching fraction of Ds+→ K+π+π− is measured to be (6.11 ± 0.18stat.± 0.11syst.) × 10−3. The branching fractions of the dominant intermediate processes Ds+→ K+ρ0, ρ0→ π+π− and Ds+→ K*(892)0π+, K*(892)0→ K+π− are determined to be (1.96 ± 0.19stat.± 0.23syst.) × 10−3 and (1.85 ± 0.12stat.± 0.13syst.) × 10−3, respectively. The intermediate resonances f0(500), f0(980), and f0(1370) are observed for the first time in this channel. [Figure not available: see fulltext.] © 2022, The Author(s).

The singly Cabibbosuppressed decay Ds+ → K+π+π−π0 is observed by using a data set corresponding to an integrated luminosity of 6.32 fb−1 recorded by the BESIII detector at the centreofmass energies between 4.178 and 4.226 GeV. The first amplitude analysis of Ds+ → K+π+π−π0 reveals the substructures in this decay and determines the fractions and relative phases of different intermediate processes. The dominant intermediate process is Ds+ → K*0ρ+, with a fit fraction of (40.5 ± 2.8stat. ± 1.5syst.)%. With the detection efficiency based on our amplitude analysis, the absolute branching fraction for Ds+ → K+π+π−π0 is measured to be (9.75 ± 0.54stat.± 0.17syst.) × 10−3.
