Measurement of effective $B_{s}^{0} \rightarrow J/\psi K_{S}^{0}$ lifetime using Run-II CMS data / Sadangi, Priyanka (Bhubaneswar, NISER) /CMS Collaboration
The effective lifetime for the decay $B_{s}^{0} \rightarrow J/\psi K_{S}^{0}$ is reported using the data from pp collision at centre of mass energy $\sqrt{s}$=13\,TeV recorded by CMS experiment at the LHC during 2016, 2017 and 2018. The data sample corresponds to an integrated luminosity of 140 fb$^{-1}$ . [...]

Results and Perspectives on Multi-Parton Interactions with CMS / Ascioti, Maria Elena (INFN, Perugia ; Perugia U.) /CMS Collaboration
This contribution covers recent CMS experiment studies at the LHC, including the first direct observation of Double Parton Scattering (DPS) in same-sign WW boson production at $\sqrt{s} = 13$ TeV. Interest in DPS has shifted to flavour physics due to higher production cross-sections and better detector performance, enabling CMS to rival experiments like LHCb. [...]
