Description
Physics Analysis Methods
Simulation in High Energy Phyiscs (HEP) places a heavy burden on the available computing resources and is expected to become a major bottleneck for the upcoming high luminosity phase of the LHC and for future Higgs factories, motivating a concerted effort to develop computationally efficient solutions. Methods based on generative machine learning methods hold promise to alleviate the...
LCFIPlus, a combined package for vertex finding, jet clustering and flavor tagging is a software package used as a standard tool for the jet analysis of linear colliders since 2012. As the author is one of the original developers, the overview of the software and performance on the ILD is presented. The recent development in our group, yet not finished, to improve the performance of vertex...
An important goal at future Higgs factories are precise measurements of the 125
GeV Higgs boson properties. As the Higgs boson predominantly decays
to $b\bar{b}$, the precise reconstruction of heavy flavor jets is crucial. A source
of uncertainty for these jets is missing momentum from semi-leptonic
decays $b\to\ell\nu X$. Recent work has shown the possibility of correcting
this missing...
The particle physics community has concluded that the next collider should be a Higgs factory with the ability to also produce a large number of W and Z bosons. In the ongoing discussions it has become increasingly clear that particle identification including charged hadron ID is a key feature that enables a number of analyses and improves many. A number of different PID systems - from the...
Constrained fits improve the kinematic reconstruction of the final state in many Higgs, top and electroweak physics studies. This is a powerful tool, particularly at $e^{+}e^{-} $ colliders where the initial state four-momentum is known and can be employed to constrain the final state. An accurate estimate of the measurement uncertainties, particularly for composed objects like jets, is a...
