A time-dependent amplitude analysis is performed to extract the CP-violating weak phase gamma - 2 beta (s) and, subsequently, gamma by taking the Bs0-B<overbar></mml:mover>s0 mixing phase beta (s) as an external input. The measurement yields gamma = (44 +/- 12)degrees modulo 180 degrees, where statistical and systematic uncertainties are combined. An alternative model-independent measurement, integrating over the five-dimensional phase space of the decay, yields gamma=<mml:mfenced close=")" open="(">44-13+20</mml:mfenced>degrees modulo 180 degrees. Moreover, the Bs0-B<overbar></mml:mover>s0 oscillation frequency is measured from the flavour-specific control channel Bs0 -> Ds-pi <mml:mo>+pi <mml:mo>+pi <mml:mo>- to be m(s) = (17.757 +/- 0.007(stat) +/- 0.008(syst)) ps(-1), consistent with and more precise than the current world-average value.<fig id="Figa" position="anchor"><graphic position="anchor" specific-use="HTML" mime-subtype="JPEG" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="MediaObjects/13130_2021_15094_Figa_HTML.jpg" id="MO1"></graphicPhysics, Particles & FieldsPhysicsb physicsckm angle gammacp violationhadron-hadron scattering (experiments)oscillationtext::journal::journal article::research article
