35. Mitigation of Direct APD signals in the CMS Barrel Electromagnetic Calorimeter

Catherine Cenedra Schiber (Florida State University (US))

5/21/18, 1:45 PM

Anomalous large signals are observed in the barrel region of the CMS Electromagnetic Calorimeter (ECAL) during proton-proton collisions at the LHC. They are ascribed to direct energy deposition by particles in the Avalanche Photodiodes (APDs) used for the light readout. They must be suppressed in order to prevent the spurious triggering of CMS, and to maintain the lowest possible trigger...

34. Simulation of the CMS electromagnetic calorimeter response at the energy and intensity frontier

Badder Marzocchi (Sapienza Universita e INFN, Roma I (IT))

5/21/18, 2:10 PM

The electromagnetic calorimeter (ECAL) of the CMS experiment at the LHC is a homogeneous calorimeter made of 75848 lead tungstate (PbWO_4) scintillating crystals, designed for high precision electron and photon energy measurements in hadron collisions at the TeV scale. The detailed simulation of the calorimeter response is crucial for physics analyses involving electrons, photons, jets or...

53. CMS electron and photon performance at 13 TeV

Jonas Rembser (Centre National de la Recherche Scientifique (FR))

5/21/18, 2:35 PM

The Compact Muon Solenoid (CMS) detector is one of the two multi-purpose experiments at the Large Hadron Collider (LHC) and has a broad physics program. Many aspects of this program depend on our ability to trigger, reconstruction and identify events with final state electrons, positrons, and photons with the CMS detector with excellent efficiency and high resolution.

In this talk we present...

52. New Fast Calorimeter Simulation in ATLAS

Michele Faucci Giannelli (University of Edinburgh)

5/21/18, 3:00 PM

The ATLAS physics program relies on very large samples of simulated events. Most of these samples are produced with GEANT4 which provides a detailed simulation of the ATLAS detector. However, this simulation is very time consuming. To solve this problem, fast simulation tools are used when detailed detector simulation is not needed. Until now, a fast calorimeter simulation (FastCaloSim) was...

3. CaloGAN: Simulating 3D High Energy Particle Showers in Multi-Layer Electromagnetic Calorimeters with Generative Adversarial Neural Networks

Ben Nachman (University of California Berkeley (US)), Michela Paganini (Yale University (US)), Luke Percival De Oliveira

The precise modeling of subatomic particle interactions and propagation through matter is paramount for the advancement of nuclear and particle physics searches and precision measurements. The most computationally expensive step in the simulation pipeline of a typical experiment at the Large Hadron Collider (LHC) is the detailed modeling of the full complexity of physics processes that govern...
