Energy Response and Longitudinal Shower Profiles Measured in CMS HCAL and Comparison With Geant4 / CMS HCAL Collaboration
The response of the CMS combined electromagnetic and hadron calorimeter to beams of pions with momenta in the range 5-300 GeV/c has been measured in the H2 test beam at CERN. The raw response with the electromagnetic compartment calibrated to electrons and the hadron compartment calibrated to 300 GeV pions may be represented by sigma = (1.2) sqrt{E} oplus (0.095) E. [...]

Validation of Geant4 Physics Using the CMS HCAL Test Beam 2002 Experiment / Elvira, Victor Daniel
High energy physics measurements relay to a great extent on the accuracy of physics generators and detector simulations. The size of systematic uncertainties associated with particle discoveries, mass, or cross section measurements is tightly associated with how accurately the simulations describe the actual performance of the detector in measuring physics objects.

Design, Performance, and Calibration of CMS Hadron Endcap Calorimeters / CMS HCAL Collaboration
Detailed measurements have been made with the CMS hadron calorimeter endcaps (HE) in response to beams of muons, electrons, and pions. Readout of HE with custom electronics and hybrid photodiodes (HPDs) shows no change of performance compared to readout with commercial electronics and photomultipliers. [...]

Validation of Geant4 Physics Using 1996 CMS HCAL Test Beam Data / Banerjee, Sudeshna (CERN)
Various hadronic physics models of Geant4 are validated for the first time using the 1996 test beam data of the CMS hadron calorimeter. Detailed comparison have been carried out on energy response, energy resolution and longitudinal shower profiles between the test beam data with electron and pion beams at different energies and simulation of the associated setup with different models in Geant4 and Geant3.

The CMS Barrel Calorimeter Response to Particle Beams from 2 to 350 GeV/c / CMS HCAL/ECAL Collaboration
The response of the CMS barrel calorimeter (electromagnetic plus hadronic) to hadrons, electrons and muons over a wide momentum range from 2 to 350 GeV/c has been measured. To our knowledge, this is the widest range of momenta in which any calorimeter system has been studied. [...]

Saturation and Energy Corrections for TeV Electrons and Photons / Clerbaux, Barbara ; Elgammal, Sherif ; Mahmoud, Tariq ; Marage, Pierre Edouard
This note presents a study of the response of the CMS electromagnetic calorimeter ECAL to high energy electrons and photons (from 500 to 4000 GeV), using the full simulation of the CMS detector. The longitudinal containment and the lateral extension of high energy showers are discussed, and energy and eta dependent correction factors F(E_meas, eta), where E_meas = E_ECAL + E_HCAL, are determined in order to reconstruct the incident particle energy, using the energies measured in the ECAL and in the hadronic calorimeter HCAL.

Synchronization and Timing in CMS HCAL / Baiatian, G (Yerevan Phys. Inst., Yerevan, Armenia) ; Sirunyan, Albert M ; Emeliantchik, Igor ; Massolov, V ; Shumeiko, Nikolai ; Stefanovich, R ; Damgov, Jordan ; Dimitrov, Lubomir ; Genchev, Vladimir ; Piperov, Stefan et al. /CMS Hadron Calorimeter Readout Group
The synchronization and timing of the hadron calorimeter (HCAL) for the Compact Muon Solenoid has been extensively studied with test beams at CERN during the period 2003-4, including runs with 40 MHz structured beam. The relative phases of the signals from different calorimeter segments are timed to 1 ns accuracy using a laser and equalized using programmable delay settings in the front-end electronics. [...]

Design, Performance, and Calibration of the CMS Hadron-Outer Calorimeter / CMS HCAL Collaboration
The CMS hadron calorimeter is a sampling calorimeter with brass absorber and plastic scintillator tiles with wavelength shifting fibres for carrying the light to the readout device. The barrel hadron calorimeter is complemented with an outer calorimeter to ensure high energy shower containment in the calorimeter. [...]

Validation of Geant4 Physics Models with LHC Collision Data / Banerjee, Sunanda (Fermilab) /CMS Collaboration
The CMS experiment has designed a strategy to validate Geant4 physics models using collision data from the LHC. Isolated charged particles are measured simultaneously in the tracker as well as the calorimeters. [...]

Design, Performance, and Calibration of CMS Hadron-Barrel Calorimeter Wedges / CMS HCAL Collaboration
Extensive measurements have been made with pions, electrons and muons on four production wedges of the Compact Muon Solenoid (CMS) hadron barrel (HB) calorimeter in the H2 beam line at CERN with particle momenta varying from 20 to 300 GeV/c. Data were taken both with and without a prototype electromagnetic lead tungstate crystal calorimeter (EB) in front of the hadron calorimeter. [...]
