abstract = {We revisit the calculation of the soft gluon emission probability off a coloursinglet
q¯q system that evolves in a quark-gluon plasma. The q¯q antenna is created in the
presence of a medium and then emits a soft gluon outside. The gluon emission probability is
modified with respect to the vacuum baseline due to interactions with the medium during
the formation of the antenna and its propagation. Previous studies disregarded the former
effect and found that the medium modification to the interference pattern of the antenna was
controlled by the so-called critical angle θc, that exclusively depends on medium properties.
We find that accounting for medium interactions during the antenna formation enhances
the total rate of emissions off the q¯q antenna. Interestingly, it also promotes the notion of
a critical angle to a dynamic quantity, denoted ˜θc, that depends on both the medium and
the antenna properties and is thus different for every splitting. As a consequence, depending
on the region of parameter space, colour decoherence can either be delayed or accelerated
with respect to previous estimates},
