Abstract: So far the squarks have not been detected at the LHC indicating that they are heavier than a few hundred GeVs, if they exist. The lighter stop can be considerably lighter than the other squarks. In this talk, the possibility that a supersymmetric partner of the top quark, stop, is the next-to-lightest supersymmetric particle in the constrained supersymmetric standard model is studied. We’ll find that it cannot be ruled out. Observing this kind of stop at the LHC may be difficult. theory-wide@nikhef.nl (Nikhef Theory) Thu, 16 Feb 2012 14:00:00 +0100 Date: 26-01-12 14:00 (Room H331)

Abstract: In this talk I will introduce the point of view that a successful inflationary stage of the early Universe is mainly due to a (gravitational) friction acting on the Inflaton. In this respect, I will introduce a new mechanism that, by enhancing the gravitational friction, makes any scalar field good enough for inflation. In particular, I will show that within this framework, the Higgs boson and the axions are natural inflaton candidates. theory-wide@nikhef.nl (Nikhef Theory) Thu, 10 Nov 2011 14:00:00 +0100 Date: 03-11-11 14:00 (Room H331)

Abstract: We give a gentle introduction to modified gravity, explaining the possible limitations of Einstein’s theory, and how one might go about modifying it. We then introduce the Fab Four: John, Paul, George and Ringo. This is not four lads singing songs in the Cavern, but a model of modified gravity that evades Weinberg’s no theorem and points towards a possible resolution of the cosmological constant problem. If we have time, we will also discuss screening mechanisms in modified gravity. theory-wide@nikhef.nl (Nikhef Theory) Thu, 03 Nov 2011 14:00:00 +0100 Date: 27-10-11 14:00 (Room N328)

Abstract: Methods for studying jets and their substructure typically rely on the use of specific clustering algorithms. Many procedures have been developed for identifying jets as either coming from QCD or heavy particle decays using explicit information from such a jet algorithm. Recently, we introduced an alternative approach for identifying and characterizing jets by exploiting the properties of angular correlations between pairs of constituents of jets. In this talk, I will discuss this method and other applications of correlations to studying QCD and the underlying event at a hadron collider. theory-wide@nikhef.nl (Nikhef Theory) Thu, 27 Oct 2011 14:00:00 +0200 Date: 13-10-11 14:00 (Room H331)
