Perhaps you should try some spelling variations:
"particelle acceleratori" » "particle acceleration", "particle accelerations"
"article accelerators" » "particle accelerations", "particle acceleraton", "particle acceleration"
"particle accelerators" » "pparticle accelerations", "pparticle acceleraton", "pparticle acceleration", "particle accelerations"
"particle accelerator" » "particle acceleration"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("article accelerators") OR ("particelle acceleratori"))) OR ("particle accelerators"))) OR ("particle accelerator")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"article accelerators\") OR (\"particelle acceleratori\"))) or (\"particle accelerators\"))) or (\"particle accelerator\"))".
• Removing quotes may allow a broader search: (((((( article accelerators ) OR ( particelle acceleratori ))) or ( particle accelerators ))) or ( particle accelerator )).
• Adding a wildcard symbol may retrieve word variants: (((((("article accelerators") OR ("particelle acceleratori"))) or ("particle accelerators"))) or ("particle accelerator"))*.
