    "abstract": "The quantum analogue of Galileo\u0027s leaning tower experiment is revisited using\nwave packets evolving under the gravitational potential. We first calculate the\nposition detection probabilities for particles projected upwards against\ngravity around the classical turning point and also around the point of initial\nprojection, which exhibit mass dependence at both these points. We then compute\nthe mean arrival time of freely falling particles using the quantum probability\ncurrent, which also turns out to be mass dependent. The mass dependence of both\nthe position detection probabilities and the mean arrival time vanish in the\nlimit of large mass. Thus, compatibility between the weak equivalence principle\nand quantum mechanics is recovered in the macroscopic limit of the latter.",
