#CMSpaper: Highly boosted dielectron identification in proton-proton collisions at √s = 13 TeV (arXiv:2604.13320) https://arxiv.org/abs/2604.13320 #Electrons #Photons
Highly boosted dielectron identification in proton-proton collisions at $\sqrt{s}$ = 13 TeV

A new technique is developed to identify dielectrons (e$^+$e$^-$) with Lorentz boost $γ_\mathrm{L}$ $\gt$ 20 that produce one single merged cluster in the electromagnetic calorimeter of the CMS detector. The identification uses two multivariate models: one for the case where both electron tracks are reconstructed, and another where only one of the tracks is reconstructed. The efficiency is determined using proton-proton collision data collected at a center-of-mass energy of 13 TeV. Boosted J/$ψ$ mesons decaying into e$^+$e$^-$ pairs are used to estimate the efficiency of the model with two tracks, yielding an overall efficiency of 80%. The Z $\to$ $μ^+μ^-γ$ events, where the photon converts into a collimated dielectron, are used for the model with a single track, yielding an efficiency of about 60%. A dedicated energy correction for dielectron candidates is also developed using B$^\pm$ $\to$ J/$ψ$K$^\pm$ $\to$ e$^+$e$^-$K$^\pm$ data.

Highly boosted dielectron identification in proton-proton collisions at $ \sqrt{s} = $ 13 TeV

A new technique is developed to identify dielectrons ($ \mathrm{e}^+\mathrm{e}^- $) with Lorentz boost $ \gamma_{\mathrm{L}} > $ 20 that produce one single merged cluster in the electromagnetic calorimeter of the CMS detector. The identification uses two multivariate models: one for the case where both electron tracks are reconstructed, and another where only one of the tracks is reconstructed. The efficiency is determined using proton-proton collision data collected at a center-of-mass energy of 13 TeV. Boosted $ \mathrm{J}/\psi $ mesons decaying into $ \mathrm{e}^+\mathrm{e}^- $ pairs are used to estimate the efficiency of the model with two tracks, yielding an overall efficiency of 80\%. The $ \mathrm{Z}\to\mu^{+}\mu^{-}\gamma $ events, where the photon converts into a collimated dielectron, are used for the model with a single track, yielding an efficiency of about 60\%. A dedicated energy correction for dielectron candidates is also developed using $ {\mathrm{B}^{\pm}}\to\mathrm{J}/\psi\mathrm{K^{\pm}}\to\mathrm{e}^+\mathrm{e}^-\mathrm{K^{\pm}} $ data.

I have discovered a new element.

It has 13.4 protons, 8 neutrons, and 13 to 14 elections.

Every time that it gains or loses an electron, the element switches charge, which happens every 45 minutes, unless David Muir is doing the news. Then they remain stable for the duration, so as to not interrupt.

The protons and neutrons are made up of q-arks, which come in 2 flavors: strangers and things.

I call this new element Redicu-lisium.

I tell you, one day we'll run out of #electrons just like the oil and gas, then where will we be? These ai data centers are using them all up too quickly.
