Cosmological analogies in the search for new physics in high-energy collisions
/ Sanchis-Lozano, Miguel-Angel (Valencia U., IFIC ; Valencia U.) ; Sarkisyan-Grinbaum, Edward K. (CERN ; Texas U., Arlington) ; Domenech-Garret, Juan-Luis (Madrid, Polytechnic U.) ; Sanchis-Gual, Nicolas (Lisbon, IST)
In this paper, analogies between multiparticle production in high-energy collisions and the time evolution of the early universe are discussed. A common explanation is put forward under the assumption of an unconventional early state: a rapidly expanding universe before recombination (last scattering surface), followed by the CMB, later evolving up to present days, versus the formation of hidden/dark states in hadronic collisions followed by a conventional QCD parton shower yielding final-state particles.

The analysis of angular particle correlations can yield valuable insights into the initial state of matter in high-energy collisions, thereby potentially revealing the existence of Beyond the Standard Model scenarios such as Hidden Valley (HV). [...]

Microscopic simulation of xenon-based optical TPCs in the presence of molecular additives

We introduce a simulation framework for the transport of high and low energy electrons in xenon-based gaseous optical time projection chambers (OTPCs). The simulation relies on elementary cross sections (electron-atom and electron-molecule) and incorporates, in order to compute the gas scintillation, the reaction/quenching rates (atom-atom and atom-molecule) of the first 41 excited states of xenon and the relevant associated excimers, together with their radiative cascade.

Searching for hidden matter with long-range angular correlations at $e^+e^-$ colliders
/ Pérez-Ramos, Redamy (IPSA, Paris ; Paris, LPTHE) ; Sanchis-Lozano, Miguel-Angel (Valencia U., IFIC ; Valencia U.) ; Sarkisyan-Grinbaum, Edward K. (CERN ; Texas U., Arlington)
The analysis of azimuthal correlations in multiparticle production can be useful to uncover the existence of new physics beyond the Standard Model, e.g., Hidden Valley, in $e^+e^-$ annihilation at high energies. In this paper, based on previous theoretical studies and using PYTHIA8 event generator, it is found that both azimuthal and rapidity long-range correlations are enhanced due to the presence of a new stage of matter on top of the QCD partonic cascade.
