DØ Run II Level 1 Trigger Framework
And-Or Input Terms

And-Or Input Terms are divided into two classes:

• H-Terms:    Hardware And-Or Input Terms, which come directly from Level 1 Trigger Subsystems

 
• P-Terms:    Pseudo And-Or Input Terms, which are logical combinations of H-Terms. 
  P-Terms are used to implement "OR-ing" in the Level 1 Trigger Framework

Several documents describing how And-Or Input Terms are used, and how they are mapped to subsystems, are available at other sites:

• Gordon Watts maintains the Run 2 Trigger page.
   

• Levan Babukhadia maintains the Trigger Meister Pages.
   

• P-Terms are described in D0 Note 3683, available here in PostScript.
