A study of top-quark mass measurement using the lepton energy distribution at the Large Hadron Collider
Seo Hyun An, Sayaka Kawabata, Tae Jeong Kim
We present a feasibility study of top-quark mass measurement using the energy distribution of a lepton from a W boson in a top quark decay in pp collisions at the LHC. The proposed…
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…
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…
