The sPHENIX detector at Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) has a broad experimental QCD physics program that is highlighted by jets, their substructure, and open and closed heavy flavor production. To measure these observables, the sPHENIX tracking system is composed of a monolithic active pixel sensor based vertex detector (MVTX), a silicon strip detector...
sPHENIX is a state-of-the-art detector for jet and heavy flavor physics in heavy-ion collisions and going to take data at RHIC in 2023. The sPHENIX MVTX detector has excellent position resolution and vertexing capabilities, which is crucial for heavy flavor physics studies. A dedicated online software system, including the quality control and detector slow control system, is being developed....
The Silicon Tracking System (STS) is planned to be the principal tracking detector of the future CBM experiment at FAIR. It will perform charged-particle track measurement with momentum resolution better than 2% in a 1 Tm dipole-magnetic field. A main challenge for the STS is to maintain high track reconstruction efficiency throughout the projected lifetime of the experiment which means being...
The Compressed Baryonic Matter (CBM) is one of the experimental pillars at the FAIR facility. CBM focuses on the search for signal of the phase transition between hadronic and quark-gluon matter, the QCD critical endpoint, new forms of strange-matter, in-medium modifications of hadrons, and the onset of chiral symmetry restoration.
The Silicon Tracking System is the central detector for...
The purpose of J-PARC Heavy-Ion Project (J-PARC-HI) is to study very
high-baryon density matter with a heavy ion beam of 1-12AGeV. A new
heavy-ion injector and a new booster are necessary for the heavy-ion
acceleration at J-PARC. Reuse of the KEK 500-MeV booster proton
synchrotron is planned at the first stage of J-PARC-HI. The beam
intensity at the first stage is expected to achieve...
It was recently proposed that a Fixed Target (FT) program in the ALICE experiment can give access to the far backward rapidity region for p-A and Pb-A collision systems at an intermediate center of mass energy ($\sqrt{s_{\rm NN}}$ = 115 and 72 GeV for the proton and Pb beam respectively) between RHIC and SPS [1]. The structure of the nuclei can be studied at large x and as a function of the...
ALICE 3 is a next-generation heavy-ion experiment for LHC Run 5, which will
address physics questions that are not accessible with Runs 3 and 4. One of the main goals of ALICE3 is to understand the connection between heavy quark heavy quark transport and hadronisation. One such example is the measurement of azimuthal correlations between charm and anti-charm mesons. ALICE 3 would provide...
The incoming Run 3 at LHC for ALICE will be characterized by a 50-100 times larger data-taking rate, which requires a redesign of many analysis algorithms in order to meet stricter memory and computational time constraints.
This applies especially to event mixing, which is a crucial component of correlation frameworks. Mixing is a technique of selecting distinct collisions grouped by, e.g.,...
The CBM is a next-generation experiment to be operated at FAIR facility, currently under construction in Darmstadt, Germany. Its goal is to investigate the phase diagram of strongly interacting matter in the region of high baryon-net densities and moderate temperatures, using high-intensity nucleus-nucleus collisions. The setup is designed as a forward multipurpose detector capable to measure...
The Silicon Tracking System (STS) is the main tracking detector of the CBM experiment. It is designed to reconstruct trajectories of charged particles with high efficiency, to achieve momentum resolution better than 2% inside a 1 Tm magnetic field, and to be capable of identifying complex decay topologies. The main STS functional building block is the detector module. It consists of a...
Soft theorems play a fundamental role in the development of quantum field theory. In scattering processes the production of soft photons diverges in the infrared in a controlled manner. Low's theorem relates the production cross section of a process with and without additional soft photon emission by a simple formula without dependence on the details of the process. However, this simple and...
The Compressed Baryonic Matter (CBM) is one of the core experiments at the future Facility for Anti-proton and Ion Research (FAIR), Darmstadt, Germany. The Silicon Tracking System (STS) is a central detector system of CBM, placed inside a 1T magnet and with an operation temperature of about $-10 ^oC$ to keep low radiation-induced bulk current in the silicon sensors.
Due to the conditions...
The CBM experiment at FAIR aims to explore the QCD phase diagram at high net baryon density and moderate temperature by colliding heavy nuclei in the energy range 4-12 AGeV. The Muon Chamber (MuCh) detector at CBM is dedicatedly designed to detect muon pairs originating at different phases in the evolution of the fireball produced in nuclear collisions. MuCh consists...
The Electron Ion Collider(EIC) is considered to construct at Brookhaven National Laboratory. A Dual-readout Calorimeter(DRC) is proposed as the forward calorimeter of the ECCE experiment at the EIC. The DRC consisting of two optical fibers, Cherenkov and Scintillating fibers, of different hadronic and electromagnetic responses allows us to measure electromagnetic and hadronic showers...
In preparation for the LHC Run 3, which will provide collisions at higher luminosity and center-of-mass energy, the ALICE experiment has introduced new detectors in addition to upgrading the existing detectors. As a part of this upgrade, a new silicon pixel tracking detector named Muon Forward Tracker (MFT) with an excellent positional resolution is installed in the forward rapidity region. By...
