“…The corresponding |uudbb intrinsic bottom heavy-quark Fock state can account for the observation of pp → Λ b X at high x F at the ISR [133]. The presence of charm at high x in the proton structure function is also indicated by the anomalously large pp → γcX rate reported by the D0 experiment at the Tevatron [134,135].…”

The discovery of extraterrestrial neutrinos in the ∼ 30 TeV -PeV energy range by IceCube provides new constraints on high energy astrophysics. An important background to the signal are the prompt neutrinos which originate from the decay of charm hadrons produced by high energy cosmic-ray particles interacting in the Earth's atmosphere. It is conventional to use the calculations of charm hadroproduction using gluon splitting g → cc alone. However, QCD predicts an additional "intrinsic" component of the heavy quark distribution which arises from diagrams where heavy quarks are multiply connected to the proton's valence quarks. We estimate the prompt neutrino spectrum due to intrinsic charm. We find that the atmospheric prompt neutrino flux from intrinsic charm is comparable to those calculated using QCD computations not including intrinsic charm, once we normalize the intrinsic charm differential cross sections to the ISR and the LEBC-MPS collaboration data. In future, IceCube will constrain the intrinsic charm content of the proton and will contribute to one of the major questions in high energy physics phenomenology.

“…replacing the Z boson with a final-state photon, which would permit probing lower values of Q [48][49][50]. Such measurements have been made at the Tevatron [51,52] and are suggestive of IC [53]. The LHCb calorimeter system is not well suited to studying high-energy photons; however, LHCb has demonstrated that it can reconstruct and precisely measure the properties of γ conversions to e + e − [54].…”

Measurement of Z bosons produced in association with charm jets ðZcÞ in proton-proton collisions in the forward region provides a direct probe of a potential nonperturbative (intrinsic) charm component in the proton wave function. We provide a detailed study of the potential to measure Zc production at the LHCb experiment in Runs 2 and 3 of the LHC. The sensitivity to valence-like (sea-like) intrinsic charm is predicted to be hxi IC ≳ 0.3%ð1%Þ. The impact of intrinsic charm on Higgs production at the LHC, including Hc, is also discussed in detail.

We summarize an extensive Tevatron (1984Tevatron ( − 2011 electroweak physics program that involves a variety of W and Z boson precision measurements. The relevance of these studies using single and associated gauge boson production to our understanding of the electroweak sector, quantum chromodynamics and searches for new physics is emphasized. We discuss the importance of the W boson mass measurement, the W/Z boson distributions and asymmetries, and diboson studies. We highlight the recent Tevatron measurements and prospects for the final Tevatron measurements.
