180 ◦ . Both variables are studied in the phase space with enhanced contribution from
either direct or resolved events with x LO
γ variable used to split the exclusive phase space
accordingly. The part of the phase space with enhanced contribution of direct events
(x LO
γ > 0.8) is referred later on as the direct phase space. The complementary part
(x LO
γ < 0.8), with enhanced contribution from the resolved events is referred to as the
resolved phase space.
All the phase spaces defined in this section are summarised in tables 1.4 and 1.5.
