Working Group 6 Summary: Spin and 3D Structure
/ Eyser, Oleg (Brookhaven) ; Parsamyan, Bakur (CERN ; INFN, Turin ; Turin U.) ; Rogers, Ted (Old Dominion U.)
The spin and 3D structure session of the DIS2019 conference focused on recentefforts to understand nucleon structure using collinear factorization theorems, transverse momentumdependent correlation functions (TMDs), generalized parton distribution (GPDs) and similar objects.A large amount of progress in both theoretical and experimental directions was reported. We summarize some of the highlights here..

Future SIDIS measurements with a transversely polarized deuteron target at COMPASS
/ Martin, Anna (Trieste U. ; INFN, Trieste)
/Compass
Since 2005, measurements of Collins and Sivers asymmetries from the HERMES and COMPASS experiments have shown that both the transversity and the Sivers PDFs are different from zero and measurable in semi-inclusive DIS on transversely polarised targets. Most of the data were collected on proton targets, and only small event samples were collected in the early phase of the COMPASS experiment on a deuteron (6LiD) target and more recently at JLab, on 3He.

Search for new physics in CP violation with beauty and charm decays at LHCb
/ Bartolini, Matteo (Genoa U. ; INFN, Genoa)
/LHCb
LHCb is one of the four big experiments operating at LHC and it's mainly dedicatedto measurements of $C\!P$ violation and to the search for new physics in the decays ofrare hadrons containing heavy quarks. The LHCb collaboration has recently published a result which shows for the first time a compelling 5.3 $\sigma$ evidence of $C\!P$ violation in the two-body meson $D^{0}\rightarrow K^{+}K^{-}$ and $D^{0}\rightarrow \pi^{+}\pi^{-}$ decays.$C\!P$ violation in the Cabibbo-suppressed decays $D^{+}_{s} \rightarrow K^{0}_{S}\pi^{+}$, $D^{+} \rightarrow K^{0}_{S}K^{+}$, $D^{+} \rightarrow \phi \pi^{+}$ is expected to be small ($\sim10^{-3}$) due to interference between tree and penguin diagrams and thus sensible to contributions Beyond Standard Model (BSM).

Heavy flavour spectroscopy and exotic states at the LHC
/ Cardinale, Roberta (Genoa U. ; INFN, Genoa)
/LHCb
The LHC, producing huge amount of $b\bar{b}$ and $c\bar c$ pairs, is the ideal place for spectroscopy studies which are fundamental as tests and inputs for QCD models. Many of the recently observed states, which are not fitting the standard picture, are still lacking of interpretation. [...]

Z boson production in proton-lead collisions accounting for transverse momenta of initial partons
/ Kutak, Krzysztof (Cracow, INP) ; Blanco, Etienne (Cracow, INP) ; Jung, Hannes (CERN ; DESY) ; Kusina, Aleksander (Cracow, INP) ; van Hameren, Andreas (Cracow, INP)
We report on a recent calculation of inclusive Z boson production in proton-lead collisions at theLHC taking into account the transverse momenta of the initial partons [1]. In the calculation the frameworkof $k_T$-factorization has been used. [...]
