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). [...]

First Results on the Revealing of Cognate Ancestors among the Particles of the Primary Cosmic Rays That Gave Rise to Extensive Air Showers Observed by the GELATICA Network

Phys.) ; Homola, Piotr (Cracow, INP) ; Alvarez-Castillo, David E (Cracow, INP) ; Beznosko, Dmitry (Georgia Coll. State U.) ; Sarkisyan-Grinbaum, Edward K (CERN ; Texas U., Arlington) ; Bar, Olaf (Cracow Tech. U.) et al.
For the data on the observation times and directions of the motion of extensive air showers, which are observed at two stations of the GELATICA network, for the first time we apply the method we have developed previously for identifying pairs of mutually remote extensive air showers, the ancestor particles of which arose, possibly, in a single process. A brief description of the GELATICA network, a review of the properties of used samples of data on shower observations at two stations of the network during the 2019–2021 session, and the result of applying the above method to them are given.

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.

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. [...]
