Signals of composite electroweak-neutral Dark Matter: LHC/Direct Detection interplay
No full textIn a strong-coupling picture of ElectroWeak Symmetry Breaking, a composite electroweak-
neutral state in the TeV mass range, carrying a global (quasi-)conserved charge, makes a
plausible Dark Matter (DM) candidate, with the ongoing direct DM searches being pre-
cisely sensitive to the expected signals. To exploit the crucial interplay between direct DM
searches and the LHC, we consider a composite iso-singlet vector V , mixed with the hyper-
charge gauge eld, as the essential mediator of the interaction between the DM particle and
the nucleus. Based on a suitable eective chiral Lagrangian, we give the expected properties
and production rates of V , showing its possible discovery at the maximal LHC energy with
about 100 fb1 of integrated luminosity
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
General properties of multiscalar RG Flows in
No full textFixed points of scalar field theories with quartic interactions in
dimensions are considered in full generality. For such
theories it is known that there exists a scalar function of the couplings
through which the leading-order beta-function can be expressed as a gradient.
It is here proved that the fixed-point value of is bounded from below by a
simple expression linear in the dimension of the vector order parameter, .
Saturation of the bound requires a marginal deformation, and is shown to arise
when fixed points with the same global symmetry coincide in coupling space.
Several general results about scalar CFTs are discussed, and a review of known
fixed points is given
