We show that in supersymmetric models with explicit flavor lepton number violation due to soft supersymmetry breaking mass terms there could be detectable flavor lepton number violation in slepton decays. We estimate LHC discovery potential of the lepton flavor number violation in slepton decays.

CP violation in K and B decays is reviewed in the Standard Model (SM) and beyond the SM. In K decays, one is seeking first evidence for CP violation in direct K -+ ~rTr decays. This would not give a precise quantitative test for the present explanation of CP violation in terms of a phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. Such tests are provided by a variety of CP asymmetries in neu...

CP violation in K and B decays is reviewed in the Standard Model (SM) and beyond the SM. In K decays, one is seeking first evidence for CP violation in direct K → ππ decays. This would not give a precise quantitative test for the present explanation of CP violation in terms of a phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. Such tests are provided by a variety of CP asymmetries in neutra...

In this paper, we discuss the issue of responsibilities related to the fulfillment and the violation of obligations. We propose to formally define the different aspects of responsibility, namely causal responsibility, functional responsibility, liability as well as sanctions, and to examine how delegation influences these concepts. Our main aim is to identify the responsibility of each agent th...

Supersymmetry can be modified to include violation of Lorentz symmetry. Lorentz violation can occur for example spontaneously in string theory as a tiny effect at an ultraviolet energy scale or in condensed matter systems with chemical potential. We review some of the possible ways Lorentz violation can take place while preserving supersymmetry.

CP violation is now measured by three numbers: ǫ and ǫ for the K system and sin2β for B. A future measurement of the analogue of ǫ for the B system would end any possibility of a Superweaklike Theory. Future frontiers in CP violation are briefly discussed. 1 ǫ and ǫ for the K System C, P, and T have played a major role in particle physics over the last fifty years. I like to say that these were...

We investigate CP-violation effects in the bosonic sector of the Standard Model (SM) with two Higgs doublets. First we calculate the mass eigenstates of the physical neutral Higgses for small but nonzero CP-violation parameter ξ∗, and then a “forward-backward” asymmetry Afb for the decay H → W+W−Z that would be a signal of CP-violation. Although the effects are in general small (Afb = Γfb/Γ ∼ O...

Searches for experimental manifestations of CP violation have born much fruit in recent years with the discovery of direct CP violation and the first evidence of CP violation outside of the neutral kaon system. Nevertheless we still know little about CP violation: its origin remains a mystery and there is little hard evidence that it is the sole province of the standard model. Searches for CP v...
