    "abstract": "Five-quark $qqqq\\bar q$ components in the $\\Delta(1232)$ are shown to\ncontribute significantly to $\\Delta(1232)\\to N\\pi$ decay through\nquark-antiquark annihilation transitions. These involve the overlap between the\n$qqq$ and $qqqq\\bar q$ components and may be triggered by the confining\ninteraction between the quarks. With a $\\sim$ 10% admixture of five-quark\ncomponents in the $\\Delta(1232)$ the decay width can be larger by factors 2 - 3\nover that calculated in the quark model with 3 valence quarks, depending on the\ndetails of the confining interaction. The effect of transitions between the\n$qqqq\\bar q$ components themselves on the calculated decay width is however\nsmall. The large contribution of the quark-antiquark annihilation transitions\nthus may compensate the underprediction of the width of the $\\Delta(1232)$ by\nthe valence quark model, once the $\\Delta(1232)$ contains $qqqq\\bar q$\ncomponents with $\\sim$ 10% probability.",
