Charmless $b$-hadron decays at LHCb

Measurements of $C\!P$ asymmetries in charmless two-body $B$-meson decays can provide stringent tests of the Standard Model. In multibody decays, short and long-distance dynamics along with a sizeable effective weak phase in the interference between tree and penguin amplitudes can lead to a rich structure of $C\!P$ violation as a function of the phase space. We present here the latest studies of $C\!P$ violation in charmless $b$-hadron decays, in particular those with baryons in the initial and final states.
