    • m(T2): The Truth behind the glamour. 

      Barr, Alan; Lester, Christopher G.; Stephens, Phil (HEP, Cavendish Laboratory, University of Cambridge, 2003-04)
      We present the kinematic variable, mT2, which is in some ways similar to the more familiar ‘transverse-mass’, but which can be used in events where two or more particles have escaped detection. We define this variable ...
    • New formalism for QCD parton showers. 

      Gieseke, Stefan; Stephens, Phil; Webber, Bryan R. (HEP, Cavendish Laboratory, University of Cambridge, 2003-10)
      We present a new formalism for parton shower simulation of QCD jets, which incorporates the following features: invariance under boosts along jet axes, improved treatment of heavy quark fragmentation, angular-ordered ...
    • A variable for measuring masses at hadron colliders when missing energy is expected; mT2: the truth behind the glamour 

      Barr, Alan; Lester, Christopher Gorham; Stephens, Phil (Journal of Physics G: Nuclear and Particle Physics, 2003-09)
