Abstract
Single production potential of the excited muons at the SPPC-based ultimate muon-proton collider with center-of-mass energy of 116.6 TeV was analyzed. We calculated the production cross-sections and the decay widths of the excited muons with the process of µp → µ*X → γµX . We obtained the normalized transverse momentum and pseudorapidity distributions of the final-state particles to attain the kinematical cuts for the discovery of the excited muons. With these cuts, we determined the mass limits. It was shown that the discovery limits on the mass of the excited muons are 19.6 and 10.1 TeV for λ = mµ* and λ = 50 TeV, respectively.
Highlights
The Standard Model (SM), the most persuasive theory in particle physics, provides excellent agreement with the results of various experiments
In spite of the outstanding success of being able to explain many phenomena in particle physics, there are some mysteries that the SM cannot explain
It has been shown that the super proton-proton collider (SPPC)-based ultimate muon-proton collider has a significant potential for excited muon searches
Summary
The Standard Model (SM), the most persuasive theory in particle physics, provides excellent agreement with the results of various experiments. The most recent experimental results about the excited muon mass for pair and single production are provided by the OPAL and the ATLAS collaborations, respectively. Μ∗ mass exclusion limits are mμ∗ > 103.2 GeV for e+e− → μ ∗ μ∗ , and mμ∗ > 3000 GeV for pp → μμ ∗ X For these limits on the excited muon mass, the compositeness scale ( λ) is taken equal to mμ∗ , and the scaling factors are taken as f = f ′ = 1 [4].
