Near Threshold

After examination of the correlated two-pion exchange in the NN interaction in terms of chiral pion loops in the t-channel, we consider loops in the s-channel, which get lifted on mass shell in the two-pion production process. We show that the thus obtained dynamical correlations in the σ channel lead to a quantitative description of recent exclusive measuerements near threshold.

Tsallis Distribution

We study the charged pion transverse momentum(pT)spectra inp+pcollisions as a function of collision energysand event multiplicity using Tsallis distribution. This study gives an insight of the pion production process inp+pcollisions. The study covers pion spectra measured inp+pcollisions at SPS energies (6.27–17.27 GeV), RHIC energies (62.4 GeV and 200 GeV), and LHC energies (900 GeV, 2.76 TeV, and 7 TeV). The Tsallis parameters have been obtained and parameterized as a function ofs. The study suggests that as we move to higher energy more and more hard processes contribute to the spectra. We also study the charged pion spectra for different event multiplicities inp+pcollisions for LHC energies using Tsallis distribution. The variation of the Tsallis parameters as a function of event multiplicity has been obtained and their behavior is found to be independent of collision energy.

The top pions [Formula: see text] are the typical particles predicted by the top-color-assisted technicolor (TC2) model, and the observation of these particles can be regarded as the direct evidence of the TC2 model. In this paper, we study the charged and neutral top pion production process [Formula: see text]. The results show that the production rates can reach the level of tens of fb with reasonable parameter values. So one can expect that enough signals could be produced in the International Linear Collider (ILC) experiments. Furthermore, the flavor-changing (FC) decay mode [Formula: see text] is the best channel for detecting the neutral top pion, due to the clean SM background. With a large number of events and the clean background, the neutral top pion should be observable in future ILC experiments.
