| Popis: |
Low mass dimuons production has been studied in Pb-Pb collisions at 158 GeV/A . φ, ρ and ω contributions are extracted in different transverse mass and transverse energy domains. Preliminary results of the 1996 run display an increase of the φ/(ρ+ω) ratio, coming from an increase of the φ. Cross sections are presented and temperatures extracted. |
