 Search for supersymmetry in events with a photon, jets, b-jets, and missing transverse momentum in proton-proton collisions at 13 TeV A search for supersymmetry is presented based on events with at least one photon, jets, and large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of 13 TeV.

 Measurement of exclusive Upsilon photoproduction in pPb collisions with the CMS experiment / Naskar, Kousik (Bhabha Atomic Res. Ctr.) /CMS Collaboration The aim of this study is to measure exclusive photoproduction of three resonant particles, $\bf \Upsilon(1S)$, $\bf \Upsilon(2S)$ and $\bf \Upsilon(3S)$ mesons,in their $\mu^{+}\mu^{-}$ decay modes, in ultraperipheral pPb collisions.The $\bf \Upsilon(1S)$ photoproduction cross section are measured, over the rapidity range $\vert y \vert < 2.2$, as a function of the photon-proton center-of-mass energy, $W_{\gamma p}$, which provides valuable information of the gluon distribution at small values of parton fractional momenta $x$. The slope of the squared transverse momentum ($p_{T}^2$) dependent differential cross section is measured to determine the size of the production region.

 Transversity and $\Lambda$ polarization at COMPASS / Moretti, Andrea The study of $\Lambda$ polarization in Semi-Inclusive Deep Inelastic Scattering (SIDIS) with a transversely polarized target has often been suggested as a privileged way to access transversity, as the initial quark polarization can be transmitted to the hyperon and then observed via its weak decay.
