 Fine-grained calorimeters for experiments at CLIC and FCC-ee / Viazlo, Oleksandr (CERN) We present optimisation studies for detectors being designed for future $e^+e^−$ colliders such as CLIC and FCC-ee, using particle-flow calorimetry. Surrounding a large silicon tracker volume, a very fine-grained ECAL is envisaged, with 40 Si-W layers and a lateral segmentation of $5\times5~$mm$^2$.

 A clockwork solution to the flavor puzzle / Alonso, Rodrigo (CERN) ; Carmona, Adrian (Mainz U., Inst. Phys. ; U. Mainz, PRISMA) ; Dillon, Barry M. (Plymouth U.) ; Kamenik, Jernej F. (Stefan Inst., Ljubljana ; Ljubljana U.) ; Martin Camalich, Jorge (CERN ; IAC, La Laguna) ; Zupan, Jure (Cincinnati U.) We introduce a set of clockwork models of flavor that can naturally explain the large hierarchies of the Standard Model quark masses and mixing angles.

 Measurements of $\pi^\pm$, $K^\pm$ and proton yields from the surface of the T2K replica target for incoming 31 GeV/$c$ protons with the NA61/SHINE spectrometer at the CERN SPS / Abgrall, N (NA61/SHINE Collaboration) Measurements of the $\pi^\pm$, $K^\pm$, and proton double differential yields emitted from the surface of the 90 cm-long carbon target (T2K replica) were performed for the incoming 31 GeV/$c$ protons with the NA61/SHINE spectrometer at the CERN SPS using data collected during 2010 run. The double differential $\pi^\pm$ yields were measured with increased precision compared to the previously published NA61/SHINE results, while the $K^\pm$ and proton yields were obtained for the first time.
