Muon collider experiments as electron/positron beam sources: case studies of new light-particle searches
Yasuhito Sakaki, Daiki Ueda
At muon colliders, muon decays naturally produce intense electrons and positrons with unique features, namely high energies, high repetition rates, and small intrinsic uncertaintie…
Sub-GeV dark matter search at ILC beam dumps
Kento Asai, Sho Iwamoto, Maxim Perelstein +2
Light dark matter particles may be produced in electron and positron beam dumps of the International Linear Collider (ILC). We propose an experimental setup to search for such even…
The potential of the ILC beam dump for high-intensity and large-area irradiation field with atmospheric-like neutrons and muons
Yasuhito Sakaki, Shinichiro Michizono, Nobuhiro Terunuma +1
We evaluate the neutron and muon fluxes produced in the ILC beam dumps by Monte Carlo simulations and discuss their potential use in irradiation fields. We show that the beam dumps…
First Evaluation of Meson and lepton Spectra and Search for Heavy Neutral Leptons at ILC Beam Dump
Mihoko M. Nojiri, Yasuihito Sakaki, Kohsaku Tobioka +1
A beam dump experiment can be seamlessly added to the {proposed} International Linear Collider (ILC) program because the high energy electron beam should be dumped after the collis…
The International Linear Collider: Report to Snowmass 2021
Alexander Aryshev, Ties Behnke, Mikael Berggren +508
The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in the 2030s. The ILC addresses key questions for our…
Search for axion-like particles with electron and positron beams at KEK Linac
Akimasa Ishikawa, Yasuhito Sakaki, Yosuke Takubo
We propose a fixed-target experiment to search for Axion-like particles (ALPs) coupling to photons, which utilizes electron and positron beams available at KEK Linac. The sensitivi…
New physics searches at the ILC positron and electron beam dumps
Kento Asai, Sho Iwamoto, Yasuhito Sakaki +1
We study capability of the ILC beam dump experiment to search for new physics, comparing the performance of the electron and positron beam dumps. The dark photon, axion-like partic…
Search for new light particles at ILC main beam dump
Yasuhito Sakaki, Daiki Ueda
We perform a feasibility study of a beam dump experiment at the International Linear Collider (ILC). To investigate the sensitivity to new light particles at the experiment, we con…
Implementation of muon pair production in PHITS and verification by comparing with the muon shielding experiment at SLAC
Yasuhito Sakaki, Yoshihito Namito, Toshiya Sanami +2
We implemented a model of muon pair production through a real photon in PHITS and compared our calculations with data of the muon shielding experiment conducted at SLAC to verify t…
Quark jet rates and quark/gluon discrimination in multi-jet final states
Yasuhito Sakaki
We estimate the number of quark jets in QCD multi-jet final states at hadron colliders. In the estimation, we develop the calculation of jet rates into that of quark jet rates. Fro…

Jeong Han Kim, Yasuhito Sakaki, Minho Son
We perform the combined analysis of the double Higgs production via gluon fusion in the and decay channels at the High-Luminosity LHC (HL-LHC). To va…
Parton Radiation and Fragmentation from LHC to FCC-ee
David d'Enterria, Peter Z. Skands, D. Anderle +53
This document collects the proceedings of the "Parton Radiation and Fragmentation from LHC to FCC-ee" workshop (http://indico.cern.ch/e/ee\_jets16) held at CERN in Nov. 2016. The w…
Quark-gluon discrimination in the search for gluino pair production at the LHC
Biplob Bhattacherjee, Satyanarayan Mukhopadhyay, Mihoko M. Nojiri +2
We study the impact of including quark- and gluon-initiated jet discrimination in the search for strongly interacting supersymmetric particles at the LHC. Taking the example of glu…
Evolution variable dependence of jet substructure

Studies on jet substructure have evolved significantly in recent years. Jet substructure is essentially determined by QCD radiations and non-perturbative effects. Predictions of je…
Associated jet and subjet rates in light-quark and gluon jet discrimination
Biplob Bhattacherjee, Satyanarayan Mukhopadhyay, Mihoko M. Nojiri +2
We show that in studies of light quark- and gluon-initiated jet discrimination, it is important to include the information on softer reconstructed jets (associated jets) around a p…
