Observation of a new charmed strange meson.

Charmed-strange Mesons Experimental Results

Two new states in the charm strange sector, D∗sJ(2317) + and DsJ(2460), have recently been discovered at e+e− collider experiments. The new states are first observed in the dominant Ds π0 and D∗+ s π0 modes respectively and are very narrow. They are consistent with 0+ and 1+ P-wave cs mesons. The DsJ(2460) meson is also observed in Ds γ and Ds π+π− modes. A review of the discoveries and possibl...

The Charmed Strange Meson System

Motivated by the recent surprising discovery of two new meson states with cs̄ quark content but unexpectedly low masses and narrow total decay widths, we work out, in a nonrelativistic potential-model approach developed already some two decades ago, the predictions for the energy levels of the corresponding charm–anti-strange quark bound states. In spite of the fact that this simple quark model ...

Strange and Charmed Quarks in the Nucleon

We discuss the general method of the calculation of the nucleon matrix elements of an operator associated with nonvalence quarks. The method is based on the QCD sum rules and low energy theorems. As an application of these considerations, we calculate the strange quark matrix element as well as the momentum distribution of the strangeness in the nucleon. We also calculate the singlet axial cons...

Study of cases of suicide with plaster as a new and strange way of suicide in Lorestan Province

Introduction: Suicide with plaster is a new and strange way of suicide which has been only committed in Lorestan province and its vicincy out skirts which have been occurred in recent years. Concerning the points of unclear border of this issue charactristics of victims patient's sign and symptoms, management, suitablecuring way, a study case has been done. Materials & Methods: This study co...
