Search for anomalous top quark couplings with the D0 detector
D0 Collaboration, V. Abazov
Anomalous Wtb couplings modify the angular correlations of the top quark decay products and change the single top quark production cross section. We present limits on anomalous top…
Delayed coupling theory of vertebrate segmentation
Luis G. Morelli, Saul Ares, Leah Herrgen +3
Rhythmic and sequential subdivision of the elongating vertebrate embryonic body axis into morphological somites is controlled by an oscillating multicellular genetic network termed…
Quantifiers for randomness of chaotic pseudo random number generators
L. De Micco, H. A. Larrondo, A. Plastino +1
We deal with randomness-quantifiers and concentrate on their ability do discern the hallmark of chaos in time-series used in connection with pseudo random number generators (PRNG).…
On Born-Infeld Gravity in Weitzenbock spacetime
Rafael Ferraro, Franco Fiorini
Using the Teleparallel Equivalent of General Relativity formulated in Weitzenböck spacetime, we thoroughly explore a kind of Born-Infeld regular gravity leading to second order fie…
On the accuracy of the PFA: analogies between Casimir and electrostatic forces
Francisco D. Mazzitelli, Fernando C. Lombardo, Paula I. Villar
We present an overview of the validity of the Proximity Force Approximation (PFA) in the calculation of Casimir forces between perfect conductors for different geometries, with par…
Finite-dimensional pointed Hopf algebras with alternating groups are trivial
N. Andruskiewitsch, F. Fantino, M. Graña +1
It is shown that Nichols algebras over alternating groups A_m, m>4, are infinite dimensional. This proves that any complex finite dimensional pointed Hopf algebra with group of gro…
