“…With the LHC at CERN ushering in a new era of TeV-scale high energy physics, it is worthwhile to reinvestigate this phenomenon in a new energy regime. In our previous work [3], we found that intermittent phenomenon exists in pp collisions at s = 7 TeV. That motivates our current investigation, where the analysis is extended to include the other available energies in Run 1 from the CERN Open Data Portal -0.9 and 8 TeV from the CMS collaboration.…”

The intermittency-type fluctuations as outlined by Bialas and Peschanski in the 1980s is analysed in pppp collisions at \sqrt{s}=s= 0.9, 7 and 8 TeV from the CMS collaboration at CERN. Our preliminary analysis shows that the intermittency exponents in the bin-averaged scaled factorial moments decrease in magnitude with increasing collision energy at the TeV scale, which suggests that the cascading nature of multiparticle production described by the \alphaα-model is weakening. We outline possible areas planned for future studies.

The microscopic dynamics of particle collisions is imprinted into the statistical properties of asymptotic energy flux, much like the dynamics of inflation is imprinted into the cosmic microwave background. This energy flux is characterized by correlation functions $$ \left\langle \mathcal{E}\left({\overrightarrow{n}}_1\right)\cdots \mathcal{E}\left({\overrightarrow{n}}_k\right)\right\rangle $$ E n → 1 ⋯ E n → k of energy flow operators $$ \mathcal{E}\left(\overrightarrow{n}\right) $$ E n → . There has been significant recent progress in studying energy flux, including the calculation of multi-point correlation functions and their direct measurement inside high-energy jets at the Large Hadron Collider (LHC). In this paper, we build on these advances by defining a notion of “celestial non-gaussianity” as a ratio of the three-point function to a product of two-point functions. We show that this celestial non-gaussianity is under perturbative control within jets at the LHC, allowing us to cleanly access the non-gaussian interactions of quarks and gluons. We find good agreement between perturbative calculations of the non-gaussianity and a charged-particle-based analysis using CMS Open Data, and we observe a strong non-gaussianity peaked in the “flattened triangle” regime. The ability to robustly study three-point correlations is a significant step in advancing our understanding of jet substructure at the LHC. We anticipate that the celestial non-gaussianity, and its generalizations, will play an important role in the development of higher-order parton showers simulations and in the hunt for ever more subtle signals of potential new physics within jets.

The microscopic dynamics of particle collisions is imprinted into the statistical properties of asymptotic energy flux, much like the dynamics of inflation is imprinted into the cosmic microwave background. This energy flux is characterized by correlation functions E( n 1 ) • • • E( n k ) of energy flow operators E( n). There has been significant recent progress in studying energy flux, including the calculation of multi-point correlation functions and their direct measurement inside high-energy jets at the Large Hadron Collider (LHC).
