Perhaps you should try some spelling variations:
"particles accelerated" » "particles acceleration", "lattices accelerated", "particle accelerators"
"partially accelerated" » "partially correlated", "partially integrated", "naturally accelerate"
"particle accelerator" » "particle accelerators", "particle acceleration"
"particle accelerated" » "particle accelerators", "particle acceleration", "practice accelerated", "particle acceleratorsd", "particle accelerationd"
"particle acceleraton" » "particle acceleration", "particles acceleration", "particle accelerations"
"particle accelerate" » "particle accelerators", "particle acceleration", "practice accelerate"

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: (("particle accelerator") OR ((((("particle accelerate") OR ("particles accelerated"))) OR ((((("particle accelerated") OR ("partially accelerated"))) OR ("particle acceleraton")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"particle accelerator\") or (((((\"particle accelerate\") OR (\"particles accelerated\"))) or (((((\"particle accelerated\") or (\"partially accelerated\"))) or (\"particle acceleraton\"))))))".
• Removing quotes may allow a broader search: (( particle accelerator ) or ((((( particle accelerate ) OR ( particles accelerated ))) or ((((( particle accelerated ) or ( partially accelerated ))) or ( particle acceleraton )))))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerator") or ((((("particle accelerate") OR ("particles accelerated"))) or ((((("particle accelerated") or ("partially accelerated"))) or ("particle acceleraton"))))))*.
