    Description: Author(s): Stefania Gori, Pedro Schwaller, and Carlos E. M. Wagner The minimal supersymmetric extension of the standard model (MSSM) is a well-motivated theoretical framework, which contains an extended Higgs sector, including a light Higgs with standard model-like properties in most of the parameter space. Because of the large QCD background, searches for such a H... [Phys. Rev. D 83, 115022] Published Fri Jun 24, 2011

    Description: Author(s): Wolfgang Altmannshofer, Stefania Gori, and Graham D. Kribs We explore the phenomenology of a two-Higgs-doublet model (2HDM) where both Higgs doublets couple to up-type and down-type fermions with couplings determined by the minimal flavor violation (MFV) ansatz. This 2HDM ”type MFV” generalizes 2HDM types I–IV, where the decay rates of h → b b ̅ and h → τ ... [Phys. Rev. D 86, 115009] Published Mon Dec 03, 2012

    Description: We have inverted P‐ and S‐wave travel times from seismograms recorded by a dense local network to infer the velocity structure in the crustal volume where the April 6th 2009 main shock nucleated. The goal is to image local variations of P‐wave velocity and Poisson ratio along the main shock fault zone for interpreting the complexity of the rupture history. The initial stages of the mainshock rupture are characterized by an emergent phase (EP) followed by an impulsive phase (IP) 0.87 s later. The EP phase is located in a very high VP and relatively low Poisson ratio (n) region. The IP phase marks the beginning of the large moment release and is located outside the low n volume. The comparison between the spatial variations of VP and Poisson ratio within the main shock nucleation volume inferred in this study with the rupture history imaged by inverting geophysical data allows us to interpret the delayed along strike propagation in terms of heterogeneity of lithology and material properties

    Description: We report a new model of the upper mantle structure beneath Italy obtained by means of P-wave teleseismic tomography. Besides the recent and remarkable development of the Italian Seismic Network, a high model resolution has been achieved improving the inversion method upon the ACH method used in previous investigations and picking high quality arrival times with the Multi-Channel Cross-Correlation technique. The finer details of our Vp model yield new insights into the heterogeneous structure of the Adria continental lithosphere involved in the collision between the Africa and Europe plates. A wide low Vp anomaly located in the northern Adria mantle, facing the Alpine high Vp slab, supports the idea that the Adria lithosphere has been hydrated and thinned during the Alpine subduction. We argue that this mantle softening may have played a key role in favoring the subsequent delamination of the Adria lithosphere in the northern Apennines. We hypothesize that delamination of continental lithosphere previously thinned in a back-arc setting may be considered a key process to favor subduction polarity reversal and recycling of continental material into the mantle circulation. Conversely, in the central-southern Apennines, the velocity structure is consistent with the existence of a deeper oceanic slab that flattens at the base of the upper mantle, in agreement with the widely accepted geodynamic evolution of the central Mediterranean by slab retreat and back-arc spreading. The oceanic slab is discontinuously detached from the surface plate, suggesting a different structure of the Adria lithosphere, which resists subduction instead of favoring delamination.
