We present a summary of results for SUSY Simplified Model searches at future proton colliders: the 14 TeV LHC as well as a 33 TeV proton collider and a 100 TeV proton collider. Upper limits and discovery significances are provided for the gluinoneutralino (for both light and heavy flavor decays), squark-neutralino, and gluinosquark Simplified Model planes. Events are processed with the Snowmass combined detector and Standard Model backgrounds are computed using the Snowmass samples. We place emphasis on comparisons between different collider scenarios, along with the lessons learned regarding the impact of systematic errors and pileup. More details are provided in a companion paper.

“…To consistently compare channels and colliders, we follow the 2013 Snowmass recommendations [61] and evaluate cross sections assuming the same fiducial acceptance. In practice, however, one tunes cuts to specific colliders and final states.…”

Fully automated precision predictions for heavy neutrino production mechanisms at hadron colliders

Motivated by TeV-scale neutrino mass models, we propose a systematic treatment of heavy neutrino (N ) production at hadron colliders. Our simple and efficient modeling of the vector boson fusion (VBF) W ± γ → N ℓ ± and N ℓ ± + nj signal definitions resolve collinear and soft divergences that have plagued past studies, and is applicable to other color-singlet processes, e.g., associated Higgs (W ± h), sparticle (l ±ν ℓ ), and charged Higgs (h ±± h ∓ ) production. We present, for the first time, a comparison of all leading N production modes, including both gluon fusion (GF)ν ℓ and VBF. We obtain fully differential results up to next-to-leading order (NLO) in QCD accuracy using a Monte Carlo tool chain linking FeynRules, NLOCT, and MadGraph5 aMC@NLO. Associated model files are publicly available. At the 14 TeV LHC, the leading order GF rate is small and comparable to the NLO N ℓ ± + 1j rate; at a future 100 TeV Very Large Hadron Collider, GF dominates for mN = 300 − 1500 GeV, beyond which VBF takes lead.

“…We use the Snowmass background set for 14 TeV pp colliders [28][29][30], which is briefly described in the Appendix, to estimate SM background. We generate our signal events, slepton Drell-Yan pair production, with the same tools used to generate the background set.…”

“…We use the Snowmass backgrounds for pp colliders with √ s = 14 and 100 TeV [28][29][30] as the SM background contributions. These backgrounds are available with and without pileup; for simplicity, we used the backgrounds without pile-up.…”

We study the prospects for long-lived charged particle (LLCP) searches at current and future LHC runs and at a 100 TeV pp collider, using Drell-Yan slepton pair production as an example. Because momentum measurements become more challenging for very energetic particles, we carefully treat the expected momentum resolution. At the same time, a novel feature of 100 TeV collisions is the significant energy loss of energetic muons in the calorimeter. We use this to help discriminate between muons and LLCPs. We find that the 14 TeV LHC with an integrated luminosity of 3 ab −1 can probe LLCP slepton masses up to 1.2 TeV, and a 100 TeV pp collider with 3 ab −1 can probe LLCP slepton masses up to 4 TeV, using time-of-flight measurements. These searches will have striking implications for dark matter, with the LHC definitively testing the possibility of slepton-neutralino coannihilating WIMP dark matter, and with the LHC and future hadron colliders having a strong potential for discovering LLCPs in models with superWIMP dark matter.
