The inclusive mode
The algorithm proceeds as follows:
- For every final state object1 and for
every pair and , compute the resolution variables
and . The precise definition of these variables can be chosen
by the user (using the parameter angle), and will be
described in detail in section 2.4. They always have the
property that in the small angle limit they reduce respectively to the
squared relative transverse momentum of the object with respect to the
beam direction, and the squared relative transverse momentum of one
object with respect to the other.
At this stage, a dimensionless parameter is
introduced[3], which plays a radius-like role in defining
the extent of the jets. This is usually set to 1.0.

is the smallest, and are combined into a single
object with momentum according to a user specified
recombination scheme (parameter recom) which will be
described in section 2.5. As an example, recom = 1 would
correspond to 4-vector addition. If a is the smallest, object
is defined to be a jet and is removed from the list of objects
to be merged.
- Repeat until all objects have been included in jets.
