== The Higgs Characterization model == === Authors === * Priscila de Aquino & Kentarou Mawatari * Affiliation: Vrije Universiteit Brussel * Emails: paquino @ vub.ac.be & kentarou.mawatari @ vub.ac.be === Description of the model === This is the model file for the characterization of a (125 GeV) resonance. We present a general implementation of particles with different spin/parity coupling to the SM particles. Particles introduced within this model file: X0, X1 and X2. * For requesting a 0+ particle, the user must choose ca=1; * For a 0- particle, ca=0; * For a 1- particle, kfa, kv1, kv2, kv3 !=0; * For a 1+ particle, kfb, kv4, kv5 !=0; * For a 2+ with the lowest dimensional (dim-5) operators, kf, kv, ka, kg !=0; * For a 2+ with higher dimensional (dim-7) operators, kv1, ka1, kg1 !=0 * For a 2- particle, kv2, ka2, kg2 != 0. Notice that ca (and sa) stands for cos[alpha] (and sin[alpha]) and allows the user to have a mix 0- 0+ state: X0 = cos[alpha] 0+ + sin[alpha] 0- The present model file contains parts of the following existing FR model files: * 1) HEFT, author: C. Duhr * 2) Minimal Zprime, author: L. Basso * 3) RS, author: P. de Aquino ----------------------- === Version updates === * v1.0 - Release version * v1.1 - Added the CP-odd Yukawa terms in the X0 lagrangian and modified the X2 HD lagrangian to be proportional to 1/Lambda^3 -----------------------
