Analyses techniques based on multiparticle azimuthal correlations are widely used at RHIC and LHC experiments for the measurements of anisotropic flow and related phenomena. These techniques are reliable only when the number of produced particles and the values of flow harmonics are large. This limitation originates from the fact that for flow results obtained with multiparticle correlations,...
In the ALICE experiment at LHC (CERN), the experimental study of quark gluon plasma with the world’s highest energy heavy ion collisions is being conducted for many years. From the LHC Run 3, a new silicon pixel detector, the Muon Forward Tracker (MFT), is installed in front of the muon spectrometer in order to improve the muon tracking in the forward rapidity region. The MFT is made of 5...
The Compressed Baryonic Matter (CBM), a fixed target experiment is under development at the Facility for Anti-Proton and Ion Research (FAIR) in Darmstadt (Germany). The aim of the experiment is to study the QCD phase diagram of strongly interacting matter at high density and moderate temperature employing heavy-ion beams in the energy range between 2 AGeV – 11 AGeV.
The experiment is...
The Compressed Baryonic Matter (CBM) experiment is a fixed-target heavy-ion physics experiment at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. The CBM physics program aims at exploring the QCD phase diagram at very high baryon densities, where a first-order phase transition from hadronic to partonic matter and a chiral phase transition is expected to occur. For...
Run 3 opens the high luminosity era of the LHC. Collecting vast data samples will enable measurements with unprecedented precision. ALICE aims to record all minimum bias data at the projected 1 MHz pp and 50 kHz heavy ion collision rates. The expected data processing and storage rate will reach ~3 TB/s. To meet this challenge, ALICE underwent a major upgrade of its detectors and systems. One...
Multi-charm baryons containing multiple charm quarks provide a unique window on uncovering the hadronisation mechanism in the quark-gluon plasma (QGP). The production yield of multi-charm baryons from single hard scattering is negligible compared to the one by coalescence of charm quarks from multiple hard scatterings. In Pb–Pb collisions, multi-charm baryon can be formed by a combination of...
J-PARC Heavy-Ion Project (J-PARC-HI) aims at exploring high-baryon density matter in heavy-ion collisions at 1-12 AGeV/c with high-intensity frontier heavy-ion beams. We have designed a heavy-ion acceleration scheme, where a heavy-ion beam is produced in a new heavy-ion injector consisting of a heavy-ion linac and a booster ring, and further accelerated with the existing high-intensity 3-GeV...
The ALICE 3 experiment is planed as a compact, next-generation multipurpose detector at the LHC as a follow-up to the present ALICE experiment. It will provide unprecedented tracking and vertexing capabilities down to a few tens of MeV/$c$ in pp, pA and AA collisions and will have a large rapidity coverage $|\eta|<4$. Such detector performances allow to study precisely the dielectron...
We propose to construct a forward conversion tracker at the LHC to measure photons of a few MeV in transverse momentum, so called ultra-soft photons, which have the potential to resolve the long standing "soft-photon puzzle": Several experiments have observed an excess of ultra-soft photon production with respect to the expected yield from Low's theorem, which is very fundamentally relating...
The Time Projection Chamber (TPC) is the main tracking and particle identification detector of the ALICE experiment at the CERN LHC. For Run 3, starting in 2022, interaction rates of 50 kHz in Pb-Pb collisions require a major upgrade of the TPC readout system. The Multi-Wire Proportional Chambers (MWPCs) were replaced by stacks of four Gas Electron Multiplier (GEM) foils, allowing continuous...
Single gap Resistive Plate Chambers (RPCs) are currently used in High Energy Physics (HEP) experiments for triggering (ALICE) and tracking (CBM) purposes for high efficiency (> 90%), good time resolution ($\sim$1-2 ns) and low-cost of fabrication. Multigap RPCs (MRPCs) are used for Time of Flight (TOF) measurements for their excellent time resolution. MRPCs are also potential candidates for...
The proposed high-luminosity high-energy Electron-Ion Collider (EIC) will provide a clean environment to precisely study several fundamental questions in the high energy and nuclear physics fields. A low material budget silicon vertex/tracking detector with fine spatial resolution (hit spatial resolution < 10 $\mu$m) is critical to carry out heavy flavor hadron and jet measurements at the...
