Abstract

This thesis presents data about the final state of identified hadrons produced in deep inelastic {mu}-hydrogen and {mu}-deuterium scattering at an incident beam energy of 280 GeV. The centre-of-mass energy is within the range of 4 to 20 GeV with a mean value of about 12 GeV. The fragmentation of the struck quark and the target rest into identified hadrons {pi}{sup {+-}}, K{sup {+-}}, p{sup {+-}}, Q{sup 0} and K{sup *0} + anti K{sup *0} is studied. The mean multiplicities vary as a function of W{sup 2}. For constant W{sup 2} the data gives no evidence of a Q{sup 2} dependence of the mean multiplicities except the Q{sup 2} dependence of the parton distributions. A difference between the predictions of the Lund model and the data is observed with respect to the mean multiplicities if the standard parameter set is used in the model. Semi-inclusive distributions are shown in the variables X{sub F} and mean P{sub T}{sup 2}. It is impossible to describe the mean value of P{sub T}{sup 2} as found in the data by the LUND model without inclusion of soft gluons the model. Favored and unfavored fragmentation functions of identified pions are calculated. The X{sub F} distribution  More>>

The fragmentation of the struck quark and the target rest into identified hadrons {pi}{sup {+-}}, K{sup {+-}}, p{sup {+-}}, Q{sup 0} and K{sup *0} + anti K{sup *0} is studied. The mean multiplicities vary as a function of W{sup 2}. For constant W{sup 2} the data gives no evidence of a Q{sup 2} dependence of the mean multiplicities except the Q{sup 2} dependence of the parton distributions. A difference between the predictions of the Lund model and the data is observed with respect to the mean multiplicities if the standard parameter set is used in the model. Semi-inclusive distributions are shown in the variables X{sub F} and mean P{sub T}{sup 2}. It is impossible to describe the mean value of P{sub T}{sup 2} as found in the data by the LUND model without inclusion of soft gluons the model. Favored and unfavored fragmentation functions of identified pions are calculated. The X{sub F} distribution shows that the disagreement between data and LUND model for the average multiplicities is concentrated in the central X{sub F} region and may be due to an overestimation of the multiplicities of unstable hadrons like Q, K{sup *} and others in the model. The data gives no evidence that the vectormesons Q{sup 0} and K{sup *0}+anti K {sup *0} are produced in a favoured helicity state. The probability of vektormesonproduction {xi}v (Q,{pi}) and {xi}v (K{sup *}, K) is calculated from the semi-inclusive multiplicities and found to be 0.5 {+-} 0.1 (stat). Finally the results of this work are compared to those of several {nu}(anti {nu})p and e{sup +}e{sup -} experiments. (orig.).}
