    Title: Strange and multi-strange particle production at the LHC energies with ALICE
    Author: Hippolyte, Boris
    Contributor: Hippolyte, Boris (pacrepositoryorg)
    Subject: Strangeness ; Organic Chemistry ; Large Hadron Collider ; Beams (Radiation) ; Domains ; Particle Production ; Particle Collisions
    Description: Strange quark and particle production is studied at the LHC with unprecedented high beam energies in both heavy-ion and proton-proton collisions: on the one hand, strangeness is used for investigating chemical equilibration and bulk properties; on the other hand, strange particles contribute to probe different kinematical domains, from the one where collective phenomena are at play up to the region dominated by pQCD-calculable processes. We highlight the suitability of the ALICE experiment for this topic, presenting our latest measurements and comparing them to models.

    Title: Thermodynamic limit in high-multiplicity \(pp\) collisions at \(\sqrt{s}\) = 7 TeV
    Author: Sharma, Natasha; Cleymans, Jean; Hippolyte, Boris
    Contributor: Hippolyte, Boris (pacrepositoryorg)
    Subject: Charged Particles ; Strangeness ; Collisions ; Mathematical Models ; Thermal Analysis ; Conservation ; Organic Chemistry ; Charged Particles
    Description: An analysis is made of the particle composition in the final state of \(pp\) collisions at 7 TeV as a function of the charged particle multiplicity (\(dN_{ch}/d\eta\)). The thermal model is used to determine the chemical freeze-out temperature as well as the radius and strangeness suppression factor \(\gamma_s\). Three different ensembles are used in the analysis. The grand canonical ensemble, the canonical ensemble with exact strangeness conservation and the canonical ensemble with exact baryon number, strangeness and electric charge conservation. It is shown that for the highest multiplicity class the three ensembles lead to the same result. This allows us to conclude that this multiplicity class is close to the thermodynamic limit. It is estimated that the final state in \(pp\) collisions could reach the thermodynamic limit when \(dN_{ch}/d\eta\) is larger than twenty per unit of rapidity, corresponding to about 300 particles in the final state when integrated over the full rapidity...

    Description: An analysis is made of the particle composition in the final state of $pp$ collisions at 7 TeV as a function of the charged particle multiplicity ($dN_{ch}/d\eta$). The thermal model is used to determine the chemical freeze-out temperature as well as the radius and strangeness suppression factor $\gamma_s$. Three different ensembles are used in the analysis. The grand canonical ensemble, the canonical ensemble with exact strangeness conservation and the canonical ensemble with exact baryon number, strangeness and electric charge conservation.

It is estimated that the final state in $pp$ collisions could reach the thermodynamic limit when $dN_{ch}/d\eta$ is larger than twenty per unit of rapidity, corresponding to about 300 particles in the final state when integrated over the full rapidity interval.

    Title: Using intermediate p t measurements for investigating hadron production at rhic
    Author: Hippolyte, Boris
    Subject: Physics;
    Description: We report preliminary results on identified hadrons using the ring imaging erenkov (RICH) and the time projection chamber (TPC) of the STAR detector. We aim to investigate hadron production mechanisms in high energy heavy-ion collisions as a function of transverse momentum ( p T ) and centrality for strange and non-strange flavours. We demonstrate the ability of the RICH which allows identification of , K, p in the intermediate p T region, complementing the linear energy loss method (d E /d x ) of the TPC. Preliminary measurements for Au+Au collisions at performed with the RICH, such as hadron spectra and baryon-to-meson ratios as a function of both p T and collision centrality, are compared to models proposing different hadron production mechanisms.

    Description: CMOS pixel sensors (CPS) represent a novel technological approach to building charged particle detectors. CMOS processes allow to integrate a sensing volume and readout electronics in a single silicon die allowing to build sensors with a small pixel pitch (\(\sim 20 \mu m\)) and low material budget (\(\sim 0.2-0.3\% X_0\)) per layer. These characteristics make CPS an attractive option for vertexing and tracking systems of high energy physics experiments. Moreover, thanks to the mass production industrial CMOS processes used for the manufacturing of CPS the fabrication construction cost can be significantly reduced in comparison to more standard semiconductor technologies. However, the attainable performance level of the CPS in terms of radiation hardness and readout speed is mostly determined by the fabrication parameters of the CMOS processes available on the market rather than by the CPS intrinsic potential. The permanent evolution of commercial CMOS processes towards smaller feature...
