Using LHC to Discover the Bilepton
/ Frampton, Paul H (Salento U. ; INFN, Lecce)
We discuss a minimal and simple extension of the standardelectroweak model and discuss its uniqueness properties.Its most readily testable prediction is the existence of$|Q|= |L|= 2$ gauge bosons, bileptons, which decay intolike-sign lepton pairs. We discuss how a discoverycould be made at the LHC..

Case for setting up a 10ps challenge: A step toward reconstruction-less TOF-PET
/ Lecoq, Paul (CERN) ; Morel, Christian (Marseille, CPPM) ; Prior, John (Lausanne U.)
The future generation of radiation detectors is more and more demanding on timing performance for a wide range of applications, such as particle identification in nuclear physics and high-energy physics detectors, high-resolution hadronic calorimetry in finely segmented detectors, precise event time tagging in high-luminosity accelerators, time-of-flight (TOF) techniques for PET cameras and a number of photonic applications based on single photon detection. There is in particular a consensus for gathering Europe’s multidisciplinary academic and industrial excellence around the ambitious challenge to develop a 10 ps TOF PET scanner (TOFPET). [...]

Development of a PbWO$_4$ Detector for Single-Shot Positron Annihilation Lifetime Spectroscopy at the GBAR Experiment
/ Kim, B H (Seoul Natl. U.) ; Choi, J J (Seoul Natl. U.) ; Chung, M (UNIST, Ulsan) ; Cladé, P (Paris, Lab. Kastler Brossel) ; Comini, P (IRFU, Saclay) ; Crivelli, P (Zurich, ETH) ; Crépin, P-P (Paris, Lab. Kastler Brossel) ; Dalkarov, O (Lebedev Inst.) ; Debu, P (IRFU, Saclay) ; Dodd, L (Swansea U.) et al.
We have developed a PbWO$_{4}$ (PWO) detector with a large dynamic range to measure the intensity of a positron beam and the absolute density of the ortho-positronium ($\mathrm{o-Ps}$) cloud it creates. A simulation study shows that a setup based on such detectors may be used to determine the angular distribution of the emission and reflection of $\mathrm{o-Ps}$ to reduce part of the uncertainties of the measurement.

Hybrid Imaging and Timing Ps Laser Excitation Diagnostics for Pulsed Antihydrogen Production
/ Caravita, R (CERN) ; Antonello, M (INFN, Milan ; Insubria U., Como) ; Belov, A (Moscow, INR) ; Bonomi, G (Brescia U. ; INFN, Pavia) ; Brusa, R S (Trento U. ; TIFPA-INFN, Trento) ; Caccia, M (INFN, Milan ; Insubria U., Como) ; Camper, A (CERN) ; Castelli, F (INFN, Milan ; Milan U.) ; Comparat, D (LAC, Orsay) ; Consolati, G (INFN, Milan ; Milan Polytechnic) et al.
In this work we present a hybrid detection method providing simultaneous imaging and timing information suitable for fully monitoring positronium (Ps) formation, its laser excitation, and its spatial propagation for the first trials of pulsed antihydrogen ($\bar{H}$) production through a charge-exchange reaction with trapped antiprotons ($\bar{p}$). This combined method, based on the synchronous acquisition of an EJ-200 scintillation detector and a microchannel plate (MCP) detector with a dual readout (phosphor screen image and electrical pick-up signal), allows all relevant events in the experiment to be accurately determined in time while allowing high resolution images of e$^{+}$ from Ps laser photodissociations to be acquired.
