Discrete gauge symmetry anomalies
Abstract It has been recently argued that quantum gravity effects strongly violate all non-gauge symmetries. This would suggest that all low energy discrete symmetries should be gauge symmetries,Expand

Unification and fermion mass structure.
Abstract Grand Unified Theories predict relationships between the GUT-scale quark and lepton masses. Using new data in the context of the MSSM, we update the values and uncertainties of the massesExpand

Discrete gauge symmetries and the origin of baryon and lepton number conservation in supersymmetric versions of the standard model
In the supersymmetric standard model operators of dimension 4 and 5 generically violate B and L number. One usually assumes the presence of some discrete symmetry (“matter parities”) in order toExpand

SU(2)L × U(1) symmetry breaking as a radiative effect of supersymmetry breaking in GUTs
Abstract It is shown how in a globally supersymmetric SU(3) × SU(2) × U(1) model supersymmetry breaking can, via radiative corrections, induce an effective Higgs potential which spontaneously breaksExpand

Perturbation Theory and the Parton Model in QCD
We prove that for any process which admits a parton-model interpretation, the naive parton model can be modified to include the effects of QCD interactions to all orders in perturbation theory. ThisExpand

Precision test of a Fermion mass texture
Abstract Texture zeros in the quark Yukawa matrices generally lead to precise and simple expressions for CKM matrix elements in terms of ratios of quark masses. Using the new data on b -decays weExpand

STUDY OF POTENTIALLY DANGEROUS EVENTS DURING HEAVY-ION COLLISIONS AT THE LHC: REPORT OF THE LHC SAFETY STUDY GROUP
TLDR
We review the possibility of producing dangerous objects during heavy-ion collisions at the Large Hadron Collider. Expand

SU(3) family symmetry and neutrino bi-tri-maximal mixing
Abstract The observed large mixing angles in the lepton sector may be the first signal for the presence of a non-Abelian family symmetry. However, to obtain the significant differences between theExpand

Mass determination of new states at hadron colliders
Abstract We propose an improved method for hadron-collider mass determination of new states that decay to a massive, long-lived state like the LSP in the MSSM. We focus on pair-produced new statesExpand
