Precise top-quark mass from the diphoton mass spectrum
Sayaka Kawabata, Hiroshi Yokoya
We calculate the amplitude by including the bound-state effects near their mass threshold. In terms of the non-relativistic expansion of the amplitude, the LO c…
Precise top mass determination using lepton distribution at LHC
Sayaka Kawabata
We present a new method to measure a theoretically well-defined mass of the top quark at the LHC. This method uses lepton energy distribution and has a boost-invariant nature. We p…
Towards precise top mass measurement at LHC
Sayaka Kawabata
The top quark mass plays an important role in a variety of discussions both within and beyond the Standard Model. However, a precise determination of a theoretically well-defined t…
New method for precise determination of top quark mass at LHC
Sayaka Kawabata
Current measurements of the top quark mass which have achieved a precision of less than 1 GeV involve a theoretical problem that the definition of the measured mass is ambiguous in…
New method for precise determination of top quark mass at LHC
Sayaka Kawabata
A new method to measure the mass of the top quark at the LHC is presented. This method uses lepton energy distribution and ideally does not depend on the velocity distribution of t…
Weight function method for precise determination of top quark mass at Large Hadron Collider
Sayaka Kawabata, Yasuhiro Shimizu, Yukinari Sumino +1
We propose a new method to measure a theoretically well-defined top quark mass at the LHC. This method is based on the "weight function method," which we proposed in our preceding…
Measurement of physical parameters with a weight function method and its application to the Higgs boson mass reconstruction
S. Kawabata, Y. Shimizu, Y. Sumino +1
We propose a new method to measure various physical parameters, using characteristic weight functions. This method requires only lepton energy distribution and ideally it does not…
Boost-invariant Leptonic Observables and Reconstruction of Parent Particle Mass
Sayaka Kawabata, Yasuhiro Shimizu, Yukinari Sumino +1
We propose a class of observables constructed from lepton energy distribution, which are independent of the velocity of the parent particle if it is scalar or unpolarized. These ob…
