The data are analysed by using the maximum likelihood method. Vector pair production in two-photon interactions was studied in two channels:γγ → K*0→*0 and γγ → K*+ K*−. Two photon production of γγ → K*0[kbar]*0 was investigated by analysing the K +π− K−π+ and K0 sπ0K±π± final states. The closely related reaction γγ→πeK*+ K*− was studied by analysing the final states K*0K ±π±π0and K0 sK0 s π±π−. The partial wave analysis of K*0[kbar]*0was performed using data from the K +π− K −π + final state. It was found that the reaction is dominated by the partial wave with spin, parity and helicity(JP, Jz ) = (2+, 2).","PeriodicalId":264948,"journal":{"name":"Surveys in High Energy Physics","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131136989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In these lectures I describe why limitations on CP invariance are a particularly fundamental phenomenon and what experimental information is available. The KM ansatz constitutes the minimal implementation of CP violation: without requiring unknown degrees of freedom it can reproduce the known CP phenomenology. It unequivocally predicts large or even huge CP asymmetries of various kinds in the decays of beauty hadrons. New theoretical technologies will enable us in the foreseeable future to express at least some of these predictions in a quantitatively reliable fashion. There is tremendous potential for discovering New Physics in beauty transitions. Continuing efforts in strange decays and further dedicated searches for electric dipole moments and for CP asymmetries in charm decays are likewise essential for ...","PeriodicalId":264948,"journal":{"name":"Surveys in High Energy Physics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123028900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Precise F2 measurements have been performed by H1 and ZEUS over a wide range in x from 10−5 to 0.3 and in Q2 from 0.16 to 5000 GeV2. F2, as well as the gluon momentum density xg(x, Q2), extracted from (dF2)/d ln Q2) exhibit a fast rise as x 0 which show that the proton's quark and gluon densities at small x are large. The data on F2 as well as the first measurements of the longitudinal structure function FL and the charm contribution to F2 are in agreement with DGLAP evolution. Comparison of results obtainedfor very small values of Q2 with theoretical models indicate that for x < 10−2 the transition from soft to hard scattering occurs at Q2 values below ≈ 1 GeV2. The DIS NC and CC measurements have been extended to large values of Q2 ≈ M2 W, M2 Z. For Q2 above M2 W the weak force is found to have similar strength as the electromagnetic one.
