2++glueball

Abstract

The mixing between the f 2 ð1270Þ, the f 0 2 ð1525Þ, and the 2 þþ glueball is determined and tested. The mass and the hadronic decay widths of two bodies of the G 2 are predicted. The search for the G 2 state in the radiative decay of the J=c is discussed.

Characterization of rattling in relation to thermal conductivity: Ordered half-Heusler semiconductors

“…Importantly, recently developed thermal conductivity methods based on anharmonic phonon scattering allow one to directly calculate lattice thermal conductivity. 15,[19][20][21][22] Here we use these tools in conjunction with simple parameters that can be extracted from phonon dispersions to explore these different views and to find phonon based metrics that may be useful in identifying rattling and low thermal conductivity without direct thermal conductivity calculations.…”

Charm hadron physics at BESIII

“…The comprehensive or improved measurements of three-body decays will benefit the understanding of the interplay between the weak and strong interactions in multi-body decays where theoretical predictions are poorer than two-body decays. The improved measurements of two-body decays can serve to better explore the contributions of W-exchange diagrams and final-state interactions [17,18,19,20], as well as SU(3)-flavor symmetry breaking effects [21,22,14,23,24] in D meson decays. In addition, these measurements will also help to improve background estimations in the precision measurements of D and B meson decays.…”

Generation of isolated ultra-short attosecond pulses by coherent control of the population of excited states

“…Normally, only the HHG spectra from the short trajectories are observed on axis in the gas target experimentally [20]. In other words, the harmonics spectra from long trajectories are usually not dominant on axis after considering macroscopic propagation [21].…”
