Searches for light, weakly coupled particles are an important component of the physics program at present and future colliders. A classic benchmark for a potential vector-boson mediator between the standard model and the dark sector is the hypothetical dark photon, which could be produced either directly or through a dark Higgs boson. As part of the US Snowmass process, we are studying the...
Two fermion production at the International Linear Collider (ILC) will allow sensitive indirect
searches for new interactions, e.g. such as heavy gauge boson Z ′. Tools available at ILC to
measure the chirality of such new interactions include the ILC s polarised beams and the tau lepton
polarisation.
Tau polarisation is extracted by measuring the distribution of tau decay products, and...
In the context of the Energy Frontier of Snowmass 2021, we are developing a neural network tagger for identifying the flavour of a jet with a physics focus on strange decays of Higgs bosons. The tagger will be deployed as part of prospect studies for SM H->ss measurements as well as for BSM heavy Higgs measurements, H(+)->cs, at future lepton colliders. In particular, these studies are...
We will present the motivation to study ee->ss. In addition we will present first data quality checks with recently produced two-fermion samples at 250 GeV for ILD. These checks concern in particular Kaon identification that exploit the dE/dx capabilities of the ILD-TPC.
The Standard Model(SM) can not explain why measured quark masses have different values and why the mass disparity between them. However, we can consider the energy dependence of quark mass, and these values change from measured values at a higher energy scale. Furthermore, some new particles such as SUSY contribute, this energy dependence will deviate from the SM's expectation. Based on this...
The Higgs boson decay modes to heavy $b$ and $c$ quarks are crucial for the Higgs physics studies. The presence of semileptonic decays in the jets originating from $b$ and $c$ quarks causes missing energy due to the undetectable neutrinos. A correction for the missing neutrino momenta can be derived from the decay kinematics up to a two-fold ambiguity. The correct solution can be identified by...
