Anyons are exotic low-dimensional quasiparticles whose unconventional quantum statistics extends the binary particle division into fermions and bosons. The fractional Hall regime provides a natural host, with first convincing anyon signatures recently observed through interferometry cross-correlations of colliding beams. However, is rife experimental complications, such as an anomalous tunneling density states, which impede manipulation anyons. Here we show experimentally that canonical integer can provide robust platform. Exploiting Coulomb interaction between two co-propagating channels, electron injected one channel splits charges behaving abelian Their revealed by negative dilute quasiparticle Similarly to observations, signal stems from time-domain braiding process, here involving incident spontaneously generated electron-hole pairs. Beyond limit, theoretical understanding achieved via edge magnetoplasmon description interacting channels. Our findings establish that, counter-intuitively, platform choice for exploring manipulating statistics.
