That’s two anti-up quarks and one anti-down quark.  The antiproton looks virtually identical to the proton - except that it has a negative electric charge.","thumbnail_url":"https://img.transistorcdn.com/ms0DEdWGHxRFV-iwboilxOVVMywvTeQXj3rWZPK1by4/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzE3MzEwLzE2MDk3/ODE1MDAtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
