Techniques for mass peak reconstruction in Searches for Long-Lived Heavy Neutral Leptons Decaying to a Lepton and a \(ρ\) Meson
Marzieh Bahmani, Alessandro Guida, Maral Khandan +2
The precise reconstruction of the mass peak of long-lived heavy neutral leptons (HNLs) helps to improve the sensitivity for sterile neutrino searches in both fixed-target and colli…
Model-independent extraction of matrix elements from top-quark measurements at hadron colliders
H. Lacker, A. Menzel, F. Spettel +5
Current methods to extract the quark-mixing matrix element from single-top production measurements assume that : top quarks decay into $b…
Systematic event generator tuning for the LHC
Andy Buckley, Hendrik Hoeth, Heiko Lacker +2
In this article we describe Professor, a new program for tuning model parameters of Monte Carlo event generators to experimental data by parameterising the per-bin generator respon…
CP Violation and the CKM Matrix: Assessing the Impact of the Asymmetric B Factories
J. Charles, A. Hocker, H. Lacker +6
We update the profile of the CKM matrix. The apex (rhobar,etabar) of the Unitarity Triangle is given by means of a global fit. We propose to include therein sin2alpha from the CP-v…
Interpreting CP Asymmetries in B->pi+ pi- Decays
Andreas Hoecker, Heiko Lacker, Muriel Pivk +1
We discuss methods used to interpret the measurements of CP-asymmetry in B->pi+pi- within the framework of the Standard Model. Interpretations using various theoretical inputs are…
