23. Artificial Neural Networks on FPGAs for Real-Time Energy Reconstruction of the ATLAS LAr Calorimeters

Johann Christoph Voigt (Technische Universitaet Dresden (DE))

Poster

Within the Phase-II upgrade of the LHC, the readout electronics of the ATLAS LAr Calorimeters is prepared for high luminosity operation expecting a pile-up of up to 200 simultaneous pp interactions. Moreover, the calorimeter signals of up to 25 subsequent collisions are overlapping, which increases the difficulty of energy reconstruction. Real-time processing of digitized pulses sampled at 40...

11. Autoencoder compression for high-energy physics

Georg Love Kildetoft (Lund University (SE))

Poster

Data is what drives all research forward, regardless of scientific discipline. At the Large Hadron Collider (LHC) in Switzerland, the data stream of registered events can reach about 60 million megabytes per second, making it physically impossible to save all the produced data with current storage technology. This means that data selection has to be performed at an early stage in the...

96. Development of the ATLAS Liquid Argon Calorimeter Readout Electronics for the HL-LHC

Poster

To meet new TDAQ buffering requirements and withstand the high expected radiation doses at the high-luminosity LHC, the ATLAS Liquid Argon Calorimeter readout electronics will be upgraded. Developments of low-power preamplifiers and shapers to meet low noise and excellent linearity requirements are ongoing in 130nm CMOS technology. In order to digitize the analogue signals on two gains after...

101. Measuring $CP$ nature of tau$-$lepton Yukawa coupling at the $e^-p$ collider

Dr Abhaya Kumar Swain (Physical Research Laboratory)

Poster

We study the prospect of determining the CP violating phase in $\tau - $lepton Yukawa coupling at the $e^-p$ Collider (LHeC). The beam energy that we have considered for the electron and proton is 150 GeV and 7 TeV respectively. The Higgs is produced through charged current as well as neutral neutral current process with a focus on the earlier because of the higher cross section. We have...

98. Nanosecond machine learning with BDT for high energy physics

Ben Carlson (University of Pittsburgh)

Poster

We present a novel implementation of classification using boosted decision trees (BDT) on field programmable gate arrays (FPGA). Two example problems are presented, in the binary classification of electrons vs. photons and in the selection of vector boson fusion-produced Higgs bosons vs. the rejection of the multijet processes. The firmware implementation of binary classification requiring 100...

100. Probing anomalous hZZ couplings using Higgs production in electron-proton collisions

PRAMOD SHARMA (IISER Mohali)

Poster

We probe anomalous HZZ coupling through single Higgs boson production at the Large Hadron electron collider with 60 GeV (7 TeV) of electron (proton) energy. The sensitivity of CP-even and odd anomalous couplings are measured through azimuthal angle difference between scattered electron and forward jets along with cross section as a function of luminosity. Comparative studies for HWW anomalous...

95. The ATLAS Muon RPC system upgrade for the High Luminosity LHC

Xiangyu Xie (University of Science and Technology of China (CN))

Poster

The present Resistive Plate Chambers (RPC)trigger system in the ATLAS muon barrel was designed according to a reference luminosity of 10^34 cm-2 s-1 with a safety factor of 5, with respect to the simulated background rates, corresponding to about 300 fb-1 integrated luminosity. HL-LHC will reach a 7.5 times higher luminosity, and correspondingly higher rate, an expected integrated luminosity...

99. The superthin fixed target for the LHCb experiment in Run4

Serhii Chernyshenko (National Academy of Sciences of Ukraine (UA))

Poster

Fixed target studies at the LHC energies (SNN about 80-120 GeV) are considered as a powerful tool for exploring QCD phase diagram in a weakly known domain of densities and temperatures with variety of possible peculiarities in the EOS in entrance and exit channels in high energy heavy ions collisions. The LHCb Collaboration having implemented the SMOG2 gaseous setup with a unique feature of...
