Large Hadron Collider (LHC) at CERN will provide excellent opportunity to study the production and decay of heavy mesons and baryons with high statistics. We aim at the heavy mesons in this work and calculate their fragmentation functions consistent with this machine and present their total fragmentation probabilities and average fragmentation parameters.
applying the variational method, the spinless reduced bethe-salpeter (rbs) equation is solved for the mesonic systems, and the mass spectra are obtained. the method is applied to the hamiltonian with the gaussian and hydrogen-type trial wave functions, and different potential models are examined. the results for the different potentials are in challenge in light mesons, while they are consisten...
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...

geant4 is an open source simulation toolkit based on c++, which its advantages progressively lead to applications in research domains especially modeling the biological effects of ionizing radiation at the sub-cellular scale. however, it was shown that geant4 does not give a reasonable result in the prediction of antiproton dose especially in bragg peak. one of the reasons could be lack of a re...
We give a mass formula for computing the mass spectrum of mesons. By this formula we show that there are many mesons with their masses corresponding to a prime number. In particular we show that all strange mesons are with their masses corresponding to a prime number. With these prime numbers indexing the mesons we give a classification of mesons. We set up a knot model of mesons to derive this...
Nolen-Schiffer Anomaly in mirror nuclei due to the NN interactions with isospin mixing between T=0 and T=1 mesons of the same spin and parity are investigated. With the computation of coulomb energy along with the charge symmetry breaking (CSB) effects provide a reasonably accurate description of binding energy differences between 39ca- 39k- , 41cs- 41ca mirror nuclei.
In this talk I review recent advances on the structure of the meson and baryon resonances which can be dynamically generated from the interaction of mesons or mesons and baryons. Particular emphasis is put on results involving vector mesons, which bring new light into the nature of some of the observed higher mass mesons and baryons and make predictions for new states.
