/ Feng, Jonathan L. (UC, Irvine) ; Kling, Felix (DESY) ; Reno, Mary Hall (Iowa U.) ; Rojo, Juan (NIKHEF, Amsterdam ; Vrije U., Amsterdam) ; Soldin, Dennis (Delaware U.) ; Anchordoqui, Luis A. (Lehman Coll.) ; Boyd, Jamie (CERN) ; Ismail, Ahmed (Oklahoma State U.) ; Harland-Lang, Lucian (Oxford U. ; Oxford U., Theor. Phys.) ; Kelly, Kevin J. (CERN) et al.
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located several hundred meters from the ATLAS interaction point and shielded by concrete and rock, will host a suite of experiments to probe Standard Model (SM) processes and search for physics beyond the Standard Model (BSM) [...]

The Large Hadron-Electron Collider at the HL-LHC
/ FCC-he Study Group Collaboration
The Large Hadron electron Collider, LHeC, is the means to move deep inelastic physics following HERA to the energy frontier of particle physics as it is being exploited by the HL-LHC. The paper presents a thorough update of the initial LHeC Conceptual Design Report (CDR) published in 2012. [...]

Higgs boson cross sections for the high-energy and high-luminosity LHC: cross-section predictions and theoretical uncertainty projections
/ Calderon Tazon, Alicia (Universidad de Cantabria and CSIC (ES)) ; Caola, Fabrizio (University of Durham (GB)) ; Campbell, John (Fermilab (US)) ; Francavilla, Paolo (Universita & INFN Pisa (IT)) ; Marchiori, Giovanni (Centre National de la Recherche Scientifique (FR)) ; Becker, Kathrin (Albert Ludwigs Universitaet Freiburg (DE)) ; Bertella, Claudia (Chinese Academy of Sciences (CN)) ; Bonvini, Marco (Sapienza Universita e INFN, Roma I (IT)) ; Chen, Xuan (Zuerich University (CH)) ; Frederix, Rikkert (Technische Universität Muenchen (DE)) et al.
This note summarizes the state-of-the-art predictions for the cross sections expected for Higgs boson production in the 27 TeV proton-proton collisions of a high-energy LHC, including a full theoretical uncertainty analysis. It also provides projections for the progress that may be expected on the timescale of the high-luminosity LHC and an assessment of the main limiting factors to further reduction of the remaining theoretical uncertainties..

(Milan Bicocca U.) ; Alves, A. (U. Sao Paulo (main)) et al.
The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a landscape of possibilities in the study of Higgs boson properties, Electroweak Symmetry breaking and the Standard Model in general, as well as new avenues in probing new physics beyond the Standard Model.

Impact of low-$x$ resummation on QCD analysis of HERA data
/ xFitter Developers' Team Collaboration
Fits to the final combined HERA deep-inelastic scattering cross-section data within the conventional DGLAP framework of QCD have shown some tension at low $x$ and low $Q^2$. A resolution of this tension incorporating $\ln(1/x)$-resummation terms into the HERAPDF fits is investigated using the xFitter program. [...]

A Determination of the Charm Content of the Proton

Phys.) ; Carrazza, Stefano (CERN) ; Forte, Stefano (Milan U. ; INFN, Milan) ; Guffanti, Alberto (Turin U. ; INFN, Turin) ; Hartland, Nathan P. (Oxford U., Theor.

/NNPDF Collaboration
We present an unbiased determination of the charm content of the proton, in which the charm parton distribution function (PDF) is parametrized on the same footing as the light quarks and the gluon in a global PDF analysis. This determination relies on the calculation of deep-inelastic structure functions in the FONLL scheme, generalized to account for massive charm-initiated contributions. [...]
