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. [...]
