Impedance simulations and measurements on the LHC collimators with embedded beam position monitors / Biancacci, N (CERN) ; Caspers, F (CERN) ; Kuczerowski, J (CERN) ; Métral, (CERN.) ; Mounet, N (CERN) ; Salvant, B (CERN) ; Mostacci, A (Rome U.) ; Frasciello, O (Frascati) ; Zobov, M (Frascati)
The LHC collimation system is a critical element for the safe operation of the LHC machine. The necessity of fast accurate positioning of the collimator’s jaws, recently introduced the need to have button beam position monitors directly embedded in the jaws extremities of the LHC tertiary collimators and some secondary collimators.

Experimental overview on flow observables in heavy ion collisions / Mohapatra, Soumya (Columbia U.)
This paper summarizes the experimental results on flow phenomena that were presented at Quark matter 2015, with a focus on new flow observables and correlations in small systems. The results presented include event-shape selected pT spectra and vn measurements, correlations between flow harmonics of different orders, study of factorization breakdown in two-particle correlations, and principal component analysis of two-particle correlations.

Measurement of the Coupling Strength of Higgs to Vector Bosons in $H \to WW \to \ell \nu \ell \nu$ final state with the ATLAS detector at the LHC / Kim, Hee Yeun (Texas U., Arlington) /ATLAS
We present the measurement of the coupling strength of the Higgs boson to the two vector bosons in the H→WW→ℓνℓν channel. Results using the 25 fb -1 of data collected in 7 and 8 TeV center of mass energy by the ATLAS experiment at the LHC are presented [ATLAS Collaboration, The ATLAS Experiment at the CERN Large Hadron Collider , 2008 JINST 3 S08003].

Detection of high energy muons with sub-20 ps timing resolution using L(Y)SO crystals and SiPM readout / Benaglia, A (CERN) ; Gundacker, S (CERN) ; Lecoq, P (CERN) ; Lucchini, M T (CERN) ; Para, A (Fermilab) ; Pauwels, K (CERN) ; Auffray, E (CERN)
Precise timing capability will be a key aspect of particle detectors at future high energy colliders, as the time information can help in the reconstruction of physics events at the high collision rate expected there. Other than being used in detectors for PET, fast scintillating crystals coupled to compact Silicon Photomultipliers (SiPMs) constitute a versatile system that can be exploited to realize an ad-hoc timing device to be hosted in a larger high energy physics detector.
