We show that no glass singularity intervenes before the jamming density, which we independently determine through two distinct non-equilibrium protocols. We demonstrate that equilibrium fluid and non-equilibrium jammed states can have the same density, showing that the jamming transition cannot be the end-point of the fluid branch. %G English %2 https://hal.science/hal-01331594/document %2 https://hal.science/hal-01331594/file/1511.06182.pdf %L hal-01331594 %U https://hal.science/hal-01331594 %~ CNRS %~ L2C %~ MIPS %~ UNIV-MONTPELLIER %~ UM-2015-2021
