“…As the drive to realize next-generation accuracy in PDF analyses gains speed with preparations for the High-Luminosity LHC [107], Electron-Ion Collider [108], and Long-Baseline Neutrino Facility [109], we recommend consideration of deuteron corrections and broader nuclear effects in PDF analyses, as well as continued phenomenological and model-based studies [55,[110][111][112] of deuteron structure in parallel. Deuteron effects will become particularly unavoidable with increasing PDF precision and in PDF-benchmarking studies, most obviously for the d-PDF at x > ∼ 0.2 and beyond, but, ultimately, for consistency of the extracted gluon density and over a widening range of x.…”

Deuterium scattering experiments in CTEQ global QCD analyses: a comparative investigation

Experimental measurements in deep-inelastic scattering and lepton-pair production on deuterium targets play an important role in the flavor separation of u and d (anti)quarks in global QCD analyses of the parton distribution functions (PDFs) of the nucleon. We investigate the impact of theoretical corrections accounting for the light-nuclear structure of the deuteron upon the fitted u, d-quark, gluon, and other PDFs in the CJ15 and CT18 families of next-to-leading order CTEQ global analyses. The investigation is done using the $$L_2$$ L 2 sensitivity statistical method, which provides a common metric to quantify the strength of experimental constraints on various PDFs and ratios of PDFs in the two distinct fitting frameworks. Using the $$L_2$$ L 2 sensitivity and other approaches, we examine the compatibility of deuteron data sets with other fitted experiments under varied implementations of the deuteron corrections. We find that freely-fitted deuteron corrections modify the PDF uncertainty at large momentum fractions and will be relevant for future PDFs affecting electroweak precision measurements.

“…The use of LGADs is foreseen in the Large Hadron Collider (LHC) upgrade in cases where, in addition to good spatial resolution, excellent temporal resolution is needed to correctly determine and assign traces where there are a large number of individual interaction vertices (pile-up). In the High Luminosity upgrade of the European Laboratory for Particle Physics (CERN-HL-LHC), the pile-up factor is expected to be four times higher than in the current LHC experiments [3]. Therefore, both ATLAS and CMS plan to introduce sub-detectors in order to perform timing measurements of Minimum Ionizing Particles (MIPs) [4,5] that will require timing capabilities of the order of ~30 ps.…”

Gain suppression induced by excess carriers in Low Gain Avalanche Detectors (LGADs) has been investigated using 3 MeV protons in a nuclear microprobe. In order to modify the ionization density inside the detector, Ion Beam Induced Current (IBIC) measurements were performed at different proton beam incidence angles between 0° and 85°. The experimental results have been analyzed as a function of the ionization density projected on the multiplication layer, finding that the increase of ionization density leads to greater gain suppression. For bias voltages close to the gain onset value, this decrease in gain results into a significant distortion of the transient current waveforms measured by the Time-Resolved IBIC (TRIBIC) technique due to a deficit in the secondary holes component. For angles of incidence such that the Bragg peak falls within the sensitive volume of the detector, the formation of microplasmas modifies the behavior of the gain curves, producing an abrupt decrease in gain as the angle increases.

“…Assuming those discrepancies are a consequence of new physical degrees of freedom, it is important to study their relation with the other SM problems and the possible consequences of the physics beyond the Standard Model. The agenda of new colliders, such as the high-luminosity (HL-)LHC [4], the International Linear Collider (ILC) [5,6], the Future Circular Collider (FCC-ee) [7][8][9], or the Circular Electron Positron Collider (CEPC) [10], includes the design of experiments with the necessary capabilities to measure with higher accuracy the properties of the precision observables in order to look for new physics signals coming from the results that deviate from the SM predictions. There is also the necessity to interpret the coming experimental results and study the implications for specific UV models.…”

High-Precision Calculations of the Higgs Boson Mass

In this paper, we review the status of the computations of the perturbative quantum corrections to the Higgs boson mass in the Standard Model and in its supersymmetric extensions. In particular, supersymmetric theories require a very accurate computation of the Higgs boson mass, which includes corrections even up to the three-loop level, since their predictions are limited by theoretical uncertainties. A discussion about these uncertainties in the context of the Minimal and Next To Minimal Supersymmetric Standard Model is included.
