We report the first direct measurement of dead-cone effect at colliders, using iterative jet declustering techniques in pp collisions $\sqrt{s} = 13$ TeV. The procedure exposes splittings $\rm{D^{0}}$ mesons shower, by iteratively angular ordered C/A tree. splitting history meson initiated is mapped onto Lund Plane, where appropriate cuts can be made to suppress hadronisation effects. reported ...

We measure the mean frequencies of acoustic waves propagating toward and away from a sunspot employing a spot-centered Fourier-Hankel decomposition of p-mode amplitudes as measured from a set of observations made at the South Pole in 1991. We demonstrate that there is a significant frequency shift between the inward and outward traveling waves which is consistent with the Doppler effect of a ra...

in this paper disposition effect, selling winners and holding losers, in tehran stock exchange (tse) investment companies and its effect on these companies’ cash flows and performance using odean model has been reviewed and investigated. research findings show that the realized profit ratio is %19 higher than the realized loss ratio in all of investment companies in tse. this mean there is a be...
