Reconstructing Sparticle Mass Spectra using Hadronic Decays
Most sparticle decay cascades envisaged at the Large Hadron Collider (LHC) involve hadronic decays of intermediate particles. We use state-of-the art techniques based on the K⊥ jet algorithm to reconstruct the resulting hadronic final states for simulated LHC events in a number of benchmark supersymmetric scenarios. In particular, we show that a general method of selecting preferentially booste...
متن کاملThree - Body Decays of the Proton
The rates for the three-body proton decays p + Irlre+ are related o+ to the rate for the decay p + TI e . This is done by making an ansatz for the form of the three-body amplitude which is consistent with current algebra and with the measured TIT final state interactions. We find that the three-body decay rates are comparable with the rate for the two-body decay p -+ roe+. Submitted to Physical...
متن کاملTesting Gluino Spin with Three-Body Decays
We examine the possibility of distinguishing a supersymmetric gluino from a KaluzaKlein gluon of universal extra dimensions (UED) at the Large Hadron Collider (LHC). We focus on the case when all kinematically allowed tree-level decays of this particle are 3-body decays into two jets and a massive daughter (typically weak gaugino or Kaluza-Klein weak gauge boson). We show that the shapes of the...
متن کاملThree–Body Decays of SUSY Particles
We analyze the decays of charginos, neutralinos, gluinos and the first/second generation squarks in the Minimal Supersymmetric extension of the Standard Model, focusing on the three–body decays in scenarios where the ratio tan β of vacuum expectation values of the two Higgs doublet fields is large. We show that the three– body decays of the next–to–lightest neutralinos (lightest charginos) into...
متن کاملOn three-body B decays to charm
Important physical information can be obtained analyzing nonleptonic many-body B decays, once clean channels have been recognized and selected. Remarkable examples are the threebody modes into pairs of charmed mesons and a light pseudoscalar meson, for which one can attempt a theoretical treatment based on heavy quark and chiral light meson symmetries [1]. A few of such modes have been recently...
