高能质子-质子和质子-反质子碰撞多重数分布的差异

Difference in multiplicity distributions in proton-proton and proton-antiproton collisions at high energies

N. V. Radchenko

摘要:

质子-质子和质子-反质子碰撞中次级带电强子多重数分布在原理上是不同的。质子-反质子散射中存在三种类型的非弹性过程。第一种是胶子弦衰变产生次级强子簇。第二类是双夸克弦衰变产生的簇射,第三类是三夸克弦衰变产生的簇射。同时,质子-质子散射的非弹性过程只有两种:胶子弦簇射和双夸克弦簇射。对能量从44.5 GeV到200 GeV的质子-质子碰撞和能量从200 GeV到1800 GeV的质子-反质子碰撞,给出了多重数分布的理论描述.讨论了质子-质子多重数分布和质子-反质子多重数分布的区别。给出了LHC能区多重数分布和平均多重数的预言。

英文摘要:

Secondary charged hadrons multiplicity distributions in proton-proton and proton-antiproton collisions differ on principle. There are three types of inelastic processes in proton-antiproton scattering. The first type is production of secondary hadrons shower at gluon string decay. The second type is shower produced from two quark strings decay, the third type is shower produced from three quark strings decay. At the same time there are only two types of inelastic processes for proton-proton scattering - gluon string shower and two quark strings shower. Theoretical description of multiplicity distributions is obtained for proton-proton collisions at energies from 44.5 GeV to 200 GeV and for proton-antiproton collisions at energies from 200 GeV to 1800 GeV. The difference between proton-proton and proton-antiproton multiplicity distributions is discussed. The predictions of multiplicity distribution and mean multiplicity at LHC energy are given.
