Abstract

The NA60 experiment has studied low-mass muon pair production in proton–nucleus collisions with a system of Be, Cu, In, W, Pb and U targets, using a 400 GeV proton beam at the CERN SPS. The transverse momentum spectra of the $$\rho /\omega $$ ρ/ω and $$\phi $$ ϕ mesons are measured in the full $$p_{\mathrm {T}}$$ pT range accessible, from $$p_{\mathrm {T}}= 0$$ pT=0 up to $$2 \, {\hbox {GeV/c}}$$ 2GeV/c . The nuclear dependence of the production cross sections of the $$\eta $$ η , $$\omega $$ ω and $$\phi $$ ϕ mesons has been found to be consistent with the power law $$\sigma _{\mathrm {pA}} \propto {\mathrm {A}}^\alpha $$ σpA∝Aα , with the $$\alpha $$ α parameter increasing as a function of $$p_{\mathrm {T}}$$ pT for all the particles, and an approximate hierarchy $$\alpha _\eta \approx \alpha _\phi > \alpha _\omega $$ αη≈αϕ>αω . The cross section ratios $$\sigma _\eta /\sigma _\omega $$ ση/σω , $$\sigma _\rho /\sigma _\omega $$ σρ/σω and $$\sigma _\phi /\sigma _\omega $$ σϕ/σω have been studied as a function of the size A of the production target, and an increase of the $$\eta $$ η and $$\phi $$ ϕ yields relative to the $$\omega $$ ω is observed from p–Be to p–U collisions.

Abstract

In time of flight positron emission tomography (TOF-PET) and in particular for the EndoTOFPET-US Project (Frisch, 2013 [1] ), and other applications for high energy physics, the multi-digital silicon photomultiplier (MD-SiPM) was recently proposed (Mandai and Charbon, 2012 [2] ), in which the time of every single photoelectron is being recorded. If such a photodetector is coupled to a scintillator, the largest and most accurate timing information can be extracted from the cascade of the scintillation photons, and the most probable time of positron emission determined. The readout concept of the MD-SiPM is very different from that of the analog SiPM, where the individual photoelectrons are merely summed up and the output signal fed into the readout electronics. We have developed a comprehensive Monte Carlo (MC) simulation tool that describes the timing properties of the photodetector and electronics, the scintillation properties of the crystal and the light transfer within the crystal. In previous studies we have compared MC simulations with coincidence time resolution (CTR) measurements and found good agreement within less than 10% for crystals of different lengths (from 3 mm to 20 mm) coupled to SiPMs from Hamamatsu. In this work we will use the developed MC tool to directly compare the highest possible time resolution for both the analog and digital readout of SiPMs with different scintillator lengths. The presented studies reveal that the analog readout of SiPMs with microcell signal pile-up and leading edge discrimination can lead to nearly the same time resolution as compared to the maximum likelihood time estimation applied to MD-SiPMs. Consequently there is no real preference for either a digital or analog SiPM for the sake of achieving highest time resolution. However, the best CTR in the analog SiPM is observed for a rather small range of optimal threshold values, whereas the MD-SiPM provides stable CTR after roughly 20 registered photoelectron timestamps in the time estimator.

Abstract

The $K^+\rightarrow \pi^+ \nu \bar \nu$ decay is one of the theoretically cleanest meson decay where to look for indirect effects of new physics complementary to LHC searches. The NA62 experiment at CERN is designed to measure the branching ratio (BR) of this decay with 10\% precision. NA62 has been successfully launched in October 2014, took data in pilot runs in 2014 and 2015 reaching the final designed beam intensity. The NA62 experimental setup is illustrated and quality of data acquired in view of the final measurement is reported. The $K^+\rightarrow \pi^+ \nu \bar \nu$ decay is theoretically one of the cleanest meson decays and so a good place to look for indirect effects of new physics complementary to LHC searches. The NA62 experiment at CERN is designed to measure the branching ratio of this decay with 10\% precision. NA62 was commissioned in October 2014, took data in pilot runs in 2014 and 2015.

Abstract

The design and technology of the silicon strip detector modules for the Semiconductor Tracker (SCT) of the ATLAS experiment have been finalised in the last several years. Integral to this process has been the measurement and verification of the tracking performance of the different module types in test beams at the CERN SPS and the KEK PS. Tests have been performed to explore the module performance under various operating conditions including detector bias voltage, magnetic field, incidence angle, and state of irradiation up to 3×1014 protons per square centimetre. A particular emphasis has been the understanding of the operational consequences of the binary readout scheme. © 2004 Elsevier B.V. All rights reserved.

Abstract

The purpose of the RD2 project is to evaluate the feasibility of a silicon tracker and/or preshower detector for LHC. Irradiation studies with doses equivalent to those expected at LHC have been performed to determine the behavior of operational parameters such as leakage current, depletion voltage and charge collection during the life of the detector. The development of fast, dense, low power and low cost signal processing electronics is one of the major activities of the collaboration. We describe the first fully functional integrated analog memory chip with asynchronous read and write operations and level 1 trigger capture capabilities. A complete test beam system using this analog memory chip at 66 MHz has been successfully operated with RD2 prototype silicon detectors during various test runs. The flexibility of the electronics and readout have allowed us to easily interface our set-up to other data acquistion systems. Mechanical studies are in progress to design a silicon tracking detector with several million channels that may be operated at low (0–10°C) temperature, while maintaining the required geometrical precision. Prototype readout boards for such a detector are being developed and simulation studies are being performed to optimize the readout architecture.

Abstract

The NA60 experiment studied low-mass muon pair production in proton–nucleus (p–A) collisions using a 400 GeV proton beam at the CERN SPS. The low-mass dimuon spectrum is well described by the superposition of the two-body and Dalitz decays of the light neutral mesons η, ρ, ω, η ′ and ϕ, and no evidence of in-medium effects is found. A new high-precision measurement of the electromagnetic transition form factors of the η and ω was performed, profiting from a 10 times larger data sample than the peripheral In–In sample previously collected by NA60. Using the pole-parameterisation | F ( M ) | 2 = ( 1 − M 2 / Λ 2 ) − 2 we find Λ η − 2 = 1.934 ± 0.067 (stat.) ±0.050 (syst.) ( GeV / c 2 ) − 2 and Λ ω − 2 = 2.223 ± 0.026 (stat.) ±0.037 (syst.) ( GeV / c 2 ) − 2 . An improved value of the branching ratio of the Dalitz decay ω → μ + μ − π 0 is also obtained, with B R ( ω → μ + μ − π 0 ) = [ 1.41 ± 0.09 (stat.) ± 0.15 (syst.) ] × 10 − 4 . Further results refer to the ρ line shape and a new limit on ρ / ω interference in hadron interactions.

Abstract

The rare decay K + ! p + n n is an excellent process to probe Standard Model and indirectly search for new physics, complementary to the ongoing direct LHC searches. The NA62 experiment at CERN SPS aims to collect about 100 of such events in two years of data taking, keeping the background at the level of 10%. The physics motivation, experimental technique and status of the experiment are presented
