“…For pp and p A UPCs, we also quote the semielastic (A B γ γ − − → X H B) cross sections (with the kinematical cuts |y q ′ | > 2.5 and p q ′ T < 5 GeV/c for the radiating quark). The values we have obtained for the elastic exclusive Higgs cross sections for pp and AA (those for p A are published in this work for the first time) agree well with those found in the recent literature [9,40] except for the PbPb case where we overpredict the cross section by a factor two compared to [40] due to the absence of the exact non-overlap condition in the convolution of fluxes as discussed previously. For pp, the calculation of Khoze et al [9] makes use of the standard formula for a narrow γ γ resonance of spin J:…”

“…it avoids the hadronic overlap and breakup of the colliding beams. The fact that our γ γ cross sections agree well with other recent calculations [9,40] (see later) lends support to our approximations.…”

“…For ArAr and OO collisions, the corrections are already much smaller [48]. A comparison of the cross sections which we obtain with factorized fluxes without full non-overlap condition (see later Table II, third column) with the results for those systems using the exact non-overlap condition [40] confirms the small impact of the approximations used here.…”

“…[33] for references). Pioneering calculations for pp [34] and PbPb [35][36][37] collisions, updated more recently [9,[38][39][40], predict cross sections of a SM Higgs boson with m H = 120 GeV/c 2 in the σ pp→γ γ→H = 0.1 fb and σ PbPb→γ γ→H = 10 pb ranges respectively. Unfortunately, the small value of the pp cross section and the large event pileup 3 in pp collisions on the one hand, and the very low design luminosities expected for PbPb, on the other, preclude any real measurement of the Higgs boson in those channels.…”

We explore for the first time the possibilities to measure an intermediate-mass (m H = 115 -140 GeV/c 2 ) Standard-Model Higgs boson in electromagnetic proton-lead (p Pb) interactions at the CERN Large Hadron Collider (LHC) via its bb decay. Using equivalent Weizsäcker-Williams photon fluxes and Higgs effective field theory for the coupling γ γ → H, we obtain a leading-order cross section of the order of 0.3 pb for exclusive Higgs production in elastic (p Pb γ γ − − → p H Pb) and semielastic (p Pb γ γ − − → X H Pb) processes at √ s NN = 8.8 TeV. After applying various kinematics cuts to remove the main backgrounds (γ γ → bb and misidentified γ γ → qq events), we find that a Higgs boson with m H = 120 GeV/c 2 could be observed in the bb channel with a 3σ-significance integrating 300 pb −1 with an upgraded p A luminosity of 10 31 cm −2 s −1 . We also provide for the first time semielastic Higgs cross sections, along with elastic tt cross sections, for electromagnetic pp, p A and AA collisions at the LHC .

We explore for the first time the possibilities to measure an intermediate-mass (m H = 115 -140 GeV/c 2 ) Standard-Model Higgs boson in electromagnetic proton-lead (p Pb) interactions at the CERN Large Hadron Collider (LHC) via its b b decay. Using equivalent Weizsäcker-Williams photon fluxes and Higgs effective field theory for the coupling γ γ → H, we obtain a leading-order cross section of the order of 0.3 pb for exclusive Higgs production in elastic (p Pb γ γ − − → p H Pb) and semielastic (p Pb γ γ − − → X H Pb) processes at √ s NN = 8.8TeV. After applying various kinematics cuts to remove the main backgrounds (γ γ → b b and misidentified γ γ → q q events), we find that a Higgs boson with m H = 120 GeV/c 2 could be observed in the b b channel with a 3σ-significance integrating 300 pb −1 with an upgraded p A luminosity of 10 31 cm −2 s −1 . We also provide for the first time semielastic Higgs cross sections, along with elastic tt cross sections, for electromagnetic pp, p A and AA collisions at the LHC .
