A New Frontier of Modern Physics Research——Pomeron as a Reggeized Tensor Glueball

提出了坡密子就是质量～2.2 GeV、量子数为IGJPC＝0 +2++的张量胶子球的雷其轨迹. 高能质子-质子弹性散射微分截面的研究表明, 这个猜想与张量胶子球的实验材料完全一致的.

We propose that th e Pomeron is a Regge trajectory of tensor glueballs with the lightest member hav ing a mass in the 2.2 GeV region and the quantum numbers IGJPC = 0 + 2 ++. By using the well-established high-energy proton-proton elastic sc atter ing differential cross sections, we show that our conjecture is fully consisten t with the observed ξ production data.
