Indirect CP probes of the Higgs–top-quark interaction at the LHC [article]

Solving Scheduling Problems As The Puzzle Games Using Constraint Programming

Noppon Choosri
2018 Zenodo  
The benefit of using a grid puzzle as the model is that the method can amplify the simplicity of CP in solving practical problems.  ...  Nevertheless, the challenge of paramount importance in using this technique is how to present the operational problem in a solvable Constraint Satisfaction Problem (CSP) model.  ...  In order to solve the problem using CP, a model is required and it is typical to define the problem as Constraint Satisfaction Problem (CSP).  ...

2000 arXiv   pre-print
I summarize our recent works on the effects of flavor conserving CP violating phases in SUSY models on B and K phenomenology.  ...  In our model, we find that A b→sγ CP can be as large as ≃ ±16% if chargino is light enough, even if we impose the edm constraints.  ...  INTRODUCTION The minimal supersymmetric standard model (MSSM) has many CP violating (CPV) phases beyond the KM phase in the standard model (SM).  ...

Leptogenesis and Low-energy Observables

Gustavo C. Branco, M.N. Rebelo
2009 Nuclear Physics B - Proceedings Supplements  
We address the question of how to establish a connection between leptogenesis and low energy observables. We emphasize that such a connection only exists in the framework of flavour models.  ...  A particular example is the case of texture zeros in some of the Yukawa couplings.  ...  It is possible to impose constraints on m D in the context of special flavour models.  ...

Supersymmetric contribution to theCPasymmetry ofB→J/ψϕin the light of recentBs−B¯smeasurements

Shaaban Khalil
2006 Physical Review D  
We derive new model independent constraints on the supersymmetric extensions of the standard model from the new experimental measurements of B_s -B̅_s mass difference.  ...  Therefore, SUSY models with dominant LR flavor mixing is the only way to accommodate the apparent deviation of CP asymmetries from those expected in the standard model.  ...  In this letter, we study the constraints imposed on supersymmetric model due to these experimental limits. We derive model independent bounds on the relevant SUSY mass insertions.  ...

Frequency constrained ShiftCP modeling of neuroimaging data

2011 2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR)  
The shift invariant multi-linear model based on the CandeComp/PARAFAC (CP) model denoted ShiftCP has proven useful for the modeling of latency changes in trial based neuroimaging data [17] .  ...  To infer the number of components in the model we propose to apply automatic relevance determination by imposing priors that define the range of variation of each component of the shiftCP model and learning  ...  independence assumption is imposed for one of the two modes.  ...
