Applying Data Analytics to Storage Systems and Data Access / Chuchuk, Olga (speaker) (Université Côte d'Azur (FR)) ; Gargiulo, Federico (speaker) (Universita e sezione INFN di Napoli (IT)) ; Sciabà, Andrea (speaker) (CERN)
Join us in Zoom Meeting https://cern.zoom.us/j/93117439171?pwd=dTlmdmk3bTJIbHppcjErMEU1VzBHQT09 Meeting ID: 931 1743 9171 Passcode: 690271 Abstract Mastering the HL-LHC efficiency challenges requires an in depth understanding of the behaviour of storage systems at all levels. Using CERN IT’s Data Analytics Infrastructure, studies from the level of the experiments’ frameworks to the firmware of the hard disk drive, have been conducted to gain insight into access patterns, efficiency and reliability of the system. The impact of a site cache of different sizes was modelled using experiment access information. This allows a cost driven optimisation of cache size and networking. [...]

Study of nuclear deformation effects in Au+Au and U+U collisions from STAR experiment / Jia, Jiangyong (speaker) (Stony Brook University (US))
Nuclear deformation is a ubiqutous phenomenon for most atomic nuclei, reflecting collective motion induced by interaction between valance nucleons and shell structure. In most cases, the deformation has a quadrupole shape $\beta$ that is axially and refection symmetric, either prolate $\beta>0$ or oblate $\beta<0$. [...]

Two-particle azimuthal correlations in photo-nuclear ultra-peripheral Pb+Pb collisions at 5.02~TeV with ATLAS / Seidlitz, Blair Daniel (speaker) (University of Colorado Boulder (US))
The ultra-peripheral collisions (UPCs) of relativistic heavy ion beams lead to a diverse set of photon-nucleus interactions. The measurements of particles and their interaction produced in photo-nuclear reactions can shed light on the QCD dynamics of novel, extremely asymmetric colliding systems, with energies between those available at RHIC and the LHC.

Rapidity evolution of collision geometry from the improved TRENTo-3D model / Ke, Weiyao (speaker) (University of California, Berkeley; Lawrence-Berkeley National )
We propose a new parameterization of the three-dimensional initial condition for the application of the hydrodynamic model to relativistic heavy-ion collisions. In particular, we implement different average-energy production scaling behaviors for different rapidity regions in this proposed ansatz. [...]

Flash-3: Monte Carlo for initial energy density with correlated fluctuations / Franco, Rodrigo (speaker) (Universidade de São Paulo)
We present a new Monte Carlo that generates events based on statistics specified with any 1-point and 2-point function, including arbitrary correlations. Such a code can be useful for quickly generating events when analytic formulas are known (for example from recent derivations of CGC fluctuations), and for use in Bayesian analyses, where the initial state can be characterized by physical-meaningful parameter such as mean energy density, variance, skewness, correlation length, etc [...]

Flash-2: X(3872) production in pp with particle multiplicity / Epple, Eliane (speaker) (Los Alamos National Laboratory (US))
The last decade of hadron spectroscopy has unveiled a wealth of states that do not have the properties expected of particles composed of 2 or 3 valence quarks. Among the most intriguing of these exotics is the X(3872), which various models attempt to describe as a hadronic molecule, a compact tetraquark, an unexpected charmonium state, or their mixtures. Production in heavy ion collisions, as well as high multiplicity pp collisions, offer a new window on the properties of this poorly understood hadron. [...]

Flash-1: Measurement of $\gamma\gamma \rightarrow \mu^{+}\mu^{-}$ pairs in non-ultra peripheral Pb+Pb collisions with the ATLAS detector / Gilbert, Benjamin Jacob (speaker) (Columbia University (US))
ATLAS measurements of dimuons produced via $\gamma\gamma$ scattering processes in inelastic, non-ultra-peripheral Pb+Pb collisions at 5.02 TeV are presented using an integrated luminosity of 1.9 nb$^{−1}$. The $\gamma\gamma \rightarrow \mu^{+}\mu^{-}$ pairs are identified via selections on pair momentum asymmetry and acoplanarity, and the contribution from the heavy flavor decay background is estimated using both template and asymptotic fit methods.

Flash-4: Longitudinal structure of the initial state from 3+1D CGC simulations / Singh, Pragya (speaker) (University of Bielefeld)
We develop a framework to simulate the 3+1D dynamics of the initial energy deposition in heavy-ion collisions by taking into account the finite longitudinal extent of the colliding nuclei in the Color-Glass Condensate framework. Based on a simple model for the color charge distributions of the colliding nuclei, we demonstrate how the boost-invariant limit is recovered at high energies along with certain contrasting results that signify deviation from the high energy limit.
