Machine learning fully hadronic events with spectral functions
Mohammad Mahdi Altakach, Hadi Hassan, Sabine Kraml +2
Characterising fully hadronic events is a difficult task at hadron colliders. Signal jets from the hard process are mingled with an arbitrary number of ISR and FSR jets, leading to…
Quantum properties of heavy-fermion pairs at a lepton collider with polarised beams
Mohammad Mahdi Altakach, Priyanka Lamba, Fabio Maltoni +1
We investigate the quantum properties of heavy-fermion pairs, such as or , produced in lepton-lepton collisions with polarised beams. Focusing on spin correlation…
Quantum Information meets High-Energy Physics: Input to the update of the European Strategy for Particle Physics
Yoav Afik, Federica Fabbri, Matthew Low +68
Some of the most astonishing and prominent properties of Quantum Mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in dedicated low-energy la…
Reinterpretation and preservation of data and analyses in HEP
Jon Butterworth, Sabine Kraml, Harrison Prosper +145
Data from particle physics experiments are unique and are often the result of a very large investment of resources. Given the potential scientific impact of these data, which goes…
Design Initiative for a 10 TeV pCM Wakefield Collider
Spencer Gessner, Jens Osterhoff, Carl A. Lindstrøm +198
This document outlines a community-driven Design Study for a 10 TeV pCM Wakefield Accelerator Collider. The 2020 ESPP Report emphasized the need for Advanced Accelerator R\&D, and…
The Linear Collider Facility (LCF) at CERN
H. Abramowicz, E. Adli, F. Alharthi +406
In this paper we outline a proposal for a Linear Collider Facility as the next flagship project for CERN. It offers the opportunity for a timely, cost-effective and staged construc…
A Linear Collider Vision for the Future of Particle Physics
H. Abramowicz, E. Adli, F. Alharthi +446
In this paper we review the physics opportunities at linear colliders with a special focus on high centre-of-mass energies and beam polarisation, take a fresh look at the…
SModelS v3: Going Beyond Z2 Topologies
Mohammad Mahdi Altakach, Sabine Kraml, Andre Lessa +5
SModelS is a public tool for fast reinterpretation of LHC searches for new physics based on a large database of simplified model results. While previous versions were limited to mo…
Global LHC constraints on electroweak-inos with SModelS v2.3
Mohammad Mahdi Altakach, Sabine Kraml, Andre Lessa +4
Electroweak-inos, superpartners of the electroweak gauge and Higgs bosons, play a special role in supersymmetric theories. Their intricate mixing into chargino and neutralino mass…
SModelS v2.3: enabling global likelihood analyses
Mohammad Mahdi Altakach, Sabine Kraml, Andre Lessa +3
We present version 2.3 of SModelS, a public tool for the fast reinterpretation of LHC searches for new physics on the basis of simplified-model results. The main new features are a…
Combined constraints on dark photons and discovery prospects at the LHC and the Forward Physics Facility
Amin Aboubrahim, Mohammad Mahdi Altakach, Michael Klasen +2
Hidden sectors are ubiquitous in supergravity theories, in strings and in branes. Well motivated models such as the Stueckelberg hidden sector model could provide a candidate for d…
