These events have a total visible energy greater than 100 TeV or a center of mass energy greater than 700 GeV. Over 1000 events have been observed at mountain laboratories around the world. These experiments provide evidence for continued increase of QCD jet production above SPS PP collider energies, a possible breakdown of scaling in the fragmentation region and a continuing increase in the total cross section. In addition, the results strongly suggest a dominance of nuclei with atomic mass between 20≤A≤56 in the primary cosmic ray beam at 106−107 GeV per nucleus, in the region of the ‘bend’ of the all‐particle cosmic ray spectrum.","PeriodicalId":240164,"journal":{"name":"Intersections Between Particles and Nuclear Physics","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127898849","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}

The P‐violating NN interaction, studied in the NN system and in light nuclei, provides a unique window on the neutral current quark‐quark interaction. Results at low energy are in accord with expectations. However, surprises may occur when higher energies are studied in more detail. Sensitive probes of T‐violation via detailed balance, T‐odd correlations in γ and β‐decay, T‐odd effects in low‐energy neutron scattering, and searches for nuclear electric dipole moments (EDM) are discussed. No T‐violation is observed, but in several cases substantial improvements in the experimental sensitivity are imminent. Existing EDM limits are almost good enough to eliminate one of the leading theoretical explanations for CP violation.","PeriodicalId":240164,"journal":{"name":"Intersections Between Particles and Nuclear Physics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116751828","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}
