“…The idea of our proposed new search can be further extended to a general class of long-lived particle searches, exploring the soft limit for the displaced vertex signatures, covering the blind spots of current searches . We hope our study demonstrates and accelerates the new era of open science for particle physics [34][35][36][37][38][39][40][41][42][43].…”

A cluster of soft displaced tracks corresponds to the dark matter co-annihilation regime. The longlived regime is, in particular, motivated by the unexplored top partner physics. The background in this regime is extremely challenging to model using a traditional simulation method. We demonstrate the feasibility of handling the formidable background using the CMS Open Data. We perform this analysis to search for compressed and long-lived top partners in the 8 TeV CMS Open Data events with the integrated luminosity of 11.6 fb −1 and obtain new limits. With 15-30 GeV mass splitting between the top partner and the DM candidate, we exclude the top partner mass below 350 GeV, which is more stringent than the ATLAS and CMS results using 8 TeV data with 20 fb −1 luminosity. Our study also shows that the CMS Open Data can be a powerful tool to help physicists explore nonconventional new physics and even enable deriving new limits on exotic signals from data directly.

“…The CMS open data samples, that were used in this analysis, are based on pp collision at √ s = 8 TeV during the LHC run-I and recorded by the CMS detector in 2012. We used the two open data runs (run-B and run-C) corresponding to a total integrated luminosity of 11.6 fb −1 [30]. The data were triggered by the high level trigger HLT Mu40 eta2p1 which is a single muon trigger.…”

“…In the present results, we use the open CMS data samples provided by the CMS open data project [28], for pp collision at c.m.e of 8 TeV and corresponding to a total integrated luminosity of 11.6 f b −1 . The status, performance and opportunities for the use of the open CMS data were reported in [29,30]. In the next section, we introduce the theoretical model, in section III, we mention in abstract the CMS detector and the reconstruction techniques.…”

In this work, we present a search for Dark Matter candidate particles produced at the Large Hadron Collider, the process of the production of DM particles, alongside a new hypothetical gauge boson denoted by Z , is governed by a model called Mono-Z . The analyzed events contain dimuons plus large missing transverse momentum. The analyzed data were the CMS open Monte Carlo samples and the open data samples collected by the CMS detector for the proton-proton collisions at a center-of-mass energy of 8 TeV in 2012, which correspond to an integrated luminosity of 11.6 fb −1 . Two benchmarks scenarios were used for interpreting the data, the Dark Higgs scenario as a simplified approach of the Mono-Z model, and the effective field theory approach of the model. No evidence for the existence of dark matter candidates was found, and 95% confidence level limits were set on the mass of the Z , the mass of the dark matter candidate particle, and the cutoff scale of the effective field theory.

This analysis presents a search for Dark Matter (DM) particles using events with a Z heavy gauge boson and a large missing transverse momentum. The analyzed data were the Open Data collected by the CMS detector in proton-proton collisions at the LHC in 2012 and correspond to an integrated luminosity of 11.6 fb −1 at √ s = 8 TeV. One simplified benchmark model was used for interpreting the data, the so called Dark Higgs model, no evidence of dark matter candidates is found. 95% confidence level limits are set on both Z and dark matter masses. This is the first search for DM particles produced in association with a Z heavy gauge boson decaying to a pair of muons.
