Converse of object

• charge: It is interesting to notice that there is a huge number of events with 2 charged pions, which is impossible.

• observe: However, observing a pion moving at relative speed v the quarks would be seen orbiting at speed v orb.

• produce: Such interactions would typically produce pions and electron-positron pairs.

Adjective modifier

• neutral: The neutral pions convert directly into photons: Positrons These are identical particles to electrons, having the same characteristics.

Modifies a noun

• decay: Two red tracks forming a very small angle are most probably two gammas from a neutral pion decay.

• production: We are also developing and exploiting these strengths for photonuclear reactions leading to charge exchange and pion production.

• correlator: Testing that the pion correlator of an inverter is an example of an integration test.

• track: Brigitte Epp's new parameterisation for pion tracks in DC1 data added to jobOptions.
