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.

Signatures of new physics versus the ridge phenomenon in hadron-hadron collisions at the LHC / Sanchis-Lozano, Miguel-Angel (Valencia U., IFIC) ; Sarkisyan-Grinbaum, Edward K. (CERN ; Texas U., Arlington)
In this paper, we consider the possibility that a new stage of matter, stemming from hidden/dark sectors beyond the Standard Model, to be formed in $pp$ collisions at the LHC, can significantly modify the correlations among final-state particles. In particular, two-particle azimuthal correlations are studied by means of a Fourier series sensitive to the near-side ridge effect while assuming that hidden/dark particles decay on top of the conventional parton shower. [...]

Searching for new physics with three-particle correlations in $pp$ collisions at the LHC / Sanchis-Lozano, Miguel-Angel (CERN ; Valencia U., IFIC) ; Sarkisyan-Grinbaum, Edward K. (CERN ; Texas U., Arlington)
New phenomena involving pseudorapidity and azimuthal correlations among final state particles in $pp$ collisions at the LHC can hint at the existence of hidden sectors beyond the Standard Model. In this paper we rely on a correlated-cluster picture of multiparticle production, which was shown to account for the ridge effect, to assess the effect of a hidden sector on three-particle correlations concluding that there is a potential signature of new physics that can be directly tested by experiments using well-known techniques..

The ridge effect and three-particle correlations / Sanchis-Lozano, Miguel-Angel (Valencia U. ; Valencia U., IFIC) ; Sarkisyan-Grinbaum, Edward (CERN ; Texas U., Arlington)
Pseudorapidity and azimuthal three-particle correlations are studied based on a correlated-cluster model of multiparticle production. The model provides a common framework for correlations in proton-proton and heavy-ion collisions allowing easy comparison with the measurements. [...]

Searching for a hidden sector in multiparticle production at LHC / Sanchis-Lozano, Miguel-Angel (Valencia U., IFIC) ; Sarkisyan-Grinbaum, Edward (Texas U., Arlington ; CERN) ; Moreno-Picot, Salvador (Valencia U.)
A hidden sector beyond the Standard Model can show up in multiparticle production altering inclusive correlations and factorial cumulants of multiplicity distributions. In this report such a study is advocated with a special emphasis on the searches at LHC..

A correlated-cluster model and the ridge phenomenon in hadron–hadron collisions / Sanchis-Lozano, Miguel-Angel (Valencia U., IFIC ; Valencia U.) ; Sarkisyan-Grinbaum, Edward (CERN ; Texas U., Arlington)
A study of the near-side ridge phenomenon in hadron-hadron collisions based on a cluster picture of multiparticle production is presented. The near-side ridge effect is shown to have a natural explanation in this context provided that clusters are produced in a correlated manner in the collision transverse plane..
