We calculate the total and the pion. tn~ltiplicities based on· the multi-Regge model. The result shows" that the pion multiplicity is an order of ·magnitude smaller than the observed value.

Introduction · ,•j Since the multiple· productionphenomenon.was observed in ·the early 1930's in cosmic_ ray experiments/> a number of theoretical mod'els have been proposed to explain th.e phenomenon. 2 l · One . o( t4e , ~ost · sig:q.ificant properties of multiple production is that the products ha~e s~all transverse. ~omentum. .

The'.statistidtl model' ofHagedorn 8 > takes the first choice but the multi-peripheral model seems to take the latter. Another important property is that the multiplicity increases slowly with the incident energy. 4 > As we shall see later in this paper this property is probably not independent of the smallness of kT.

This is the main problem we are going to attack in this paper.

We think it is a nice place to check the validity of the multi-peripheral model.In § 2, several problems are considered in connection with the later calculation. We show among other things that the multiplicity of particles tends to the same as that of its anti-particle in the high energy limit. Section 3 gives the multi-Regge calculation of the pion multiplicity. In Appendix A we give the expansion formula for the tri-Regge region. Section 4 is devoted to the con-

“…Regge theory has been applied to reactions involving more than two particles in the final state by Kibble [110], Hong-Mo [111,112], and Shimada [113]. In this multi-particle framework, the interaction between any pair of particles is parametrized using results obtained by applying Regge theory to 2 → 2 interactions, as outlined in the previous section.…”

This document is organized as follows. The first Chapter illustrates the physical motivations of the MesonEx program, and presents the experiment. The second Chapter describes the CLAS spectrometer, its upgrade to CLAS12, and the new Forward Tagger Facility. Chapter 3 shows the detailed characterization of the FT-Cal components, and the results obtained from the two small-scale prototypes. Chapters 4 and 5 contain, respectively, the description of the amplitude used to generate pseudo-events for the reaction γ * p → pπ 0 η, and the analysis of the CLAS data used to validate the model and fix the free parameters. Finally, the sixth Chapter describes the full partial wave analysis performed on the MesonEx pseudo-data, used to estimate the sensitivity of the experiment to the discovery of a possible exotic meson.

“…To the best of our knowledge, this kind of process has been first observed in a Dalitz plot by the Aachen-Berlin-CERN Collaboration in the reaction π − p → π + π 0 n [16] and also in π − p → K 0 K 0 n [17]. Shortly after the experimental observation it was theoretically understood in [18]. In that paper it was explained in terms of double Regge graphs.…”
