Evidence of multifractality and constant specific heat in hadronic collisions at high energies

title: Signature of void probability scaling in high energy hadronic interactions
abstract: The rapidity gap probability in the p-AgBr interactions at 2.00 GeV/c and π-AgBr interactions at 200 and 350 GeV/c have been studied in detail. The data indicate scaling behaviour of the void probability in the central rapidity domain, which hints the validity of the linked-pair approximation for the N-particle cumulant correlation function.

title: Dilepton production phenomena in high energy hadronic collisions
abstract: Experiments over the last few years have given rise to a blizzard of new and interesting results with regard to the production of various dileptons in high energy hadronic collisions. An attempt has here been made on the basis of some new ideas about the structure of hadrons and thus on a newly proposed version of the multiple production model to explain some of the crucial features in connection with the various multiplicity--ratios, cross--section ratios and the average values of the transverse momenta of the produced dileptons. In the backdrop of the hadron--hadron and lepton--hadron collisions, the model for dilopton production proposed here has some degree of generality which is one of its main features.

title: Threshold pion production by neutrinos and the photon-neutrino weak-coupling theory
abstract: SummaryNeutral-lepton-current interactions in the threshold pion production process νn→νpπ- have been studied by the photon-neutrino weak-coupling theory. It is found that the value of dσ/dw, wherew is the ppπ- invariant mass, is of the order of 10−40 cm2/20 MeV and the general shape shows a sharp rise neur threshold before theN* production and, beyond this region, a sharp depletion occurs. These features are in excellent agreement with the experimental observations.RiassuntoSi sono, studiate le interazioni di correnti leptoniche neutre nel processo di produzione di soglia del pione, νn→νpπ-, per mezzo della teoria dell'accoppiamento debole fotoneneutrino. Si è trovato che il valore di dσ/dw, dovew è la massa invariante di pπ-`e dell'ordine, di 10−40 cm2/20 MeV e che la forma generale mostra un aumento brusco vicino alla soglia prima della produzione diN*, e che al di là di questa regione avviene una brusca diminuzione. Queste caratteristiche sono in eccellente accordo con le osservazioni sperimentali.РезумеВ рамках теории слабой связи фотона и нейтрино исследуются взаимодействия нейтральных лептонных тохов в процессе рождения пионов на пороге νn→νpπ-. Обнаружено, что величина dσ/dw гдеw представляет pπ- инвариантную массу, имеет порядок 10−40 cm2/20 МэВ и общая форма обнаруживает резкое возрастание вблизи порога перед образованиемN*, а после этой области имеет место резкое ослабление. Полученные особенности хорошо согласуются с экспериментальными наблюдениями.

title: Geometrical Aspects of Skyrmions, Reflection Group, and the Internal Symmetry of Hadrons
abstract: The topological aspects of skyrmions are studied and it is shown that hadronscan be viewed as composite states of baby skyrmions when the internal symmetrySU(3) is generated from reflection. It is shown that in an anisotropic space aparticle can move with l = 1/2 with a specific lx value, and a bosonic constituentmoving with l = 1/2 will appear as a baby skyrmion and a fermionic constituentwill appear as if a spin carrier is attached to a baby skyrmion. The associatedmagnetic field causes a strong statistical attraction which helps to form the boundstate of such constituents. The doublet of such particles having opposite lx valuesform a conformal spinor when each member behaves as a Cartan semispinor.The conformal reflection then helps us to generate the internal SU(3) symmetry,which splits as SU(3) → SU(2) × U(1), giving rise to the hadronic spectra. Thestrong interaction involves a composite cluster in such a bound system whenrearrangement of the constituents takes place preserving the direction vectors,and an elementary constituent can take part in a weak interaction, causing parityviolation. These features help us to consider elementary constituents as knownparticles like leptons.
