Distance k-Sectors Exist

Keiko Imai, Akitoshi Kawamura, Jiří Matoušek +2

The bisector of two nonempty sets P and Q in a metric space is the set of all points with equal distance to P and to Q. A distance k-sector of P and Q, where k is an integer, is a…

The RHESSI Satellite and Classes of Gamma-ray Bursts

J. Ripa, A. Meszaros, R. Hudec +2

Some articles based on the BATSE gamma-ray burst (GRB) catalog claim the existence of a third population of GRBs, besides long and short. In this contribution we wanted to verify t…

Satisfying states of triangulations of a convex n-gon

Andrea Jiménez, Marcos Kiwi, Martin Loebl

In this work we count the number of satisfying states of triangulations of a convex n-gon using the transfer matrix method. We show an exponential (in n) lower bound. We also give…

Zone Diagrams in Euclidean Spaces and in Other Normed Spaces

Akitoshi Kawamura, Jiří Matoušek, Takeshi Tokuyama

Zone diagram is a variation on the classical concept of a Voronoi diagram. Given n sites in a metric space that compete for territory, the zone diagram is an equilibrium state in t…

Energetics and performance of a microscopic heat engine based on exact calculations of work and heat distributions

Petr Chvosta, Mario Einax, Viktor Holubec +2

We investigate a microscopic motor based on an externally controlled two-level system. One cycle of the motor operation consists of two strokes. Within each stroke, the two-level s…

Search for the associated production of a b quark and a neutral supersymmetric Higgs boson which decays to tau pairs

D0 Collaboration, V. M. Abazov

We report results from a search for production of a neutral Higgs boson in association with a $b$ quark. We search for Higgs decays to $τ$ pairs with one $τ$ subsequently decaying…

High energy constraints in the octet SS-PP correlator and resonance saturation at NLO in 1/Nc

J. J. Sanz-Cillero, J. Trnka

We study the octet SS-PP correlator within resonance chiral theory up to the one-loop level, i.e., up to next-to-leading order in the 1/Nc expansion. We will require that our corre…

The k-in-a-path problem for claw-free graphs

Jiri Fiala, Marcin Kaminski, Bernard Lidicky +1

Testing whether there is an induced path in a graph spanning k given vertices is already NP-complete in general graphs when k=3. We show how to solve this problem in polynomial tim…

Renormalization and additional degrees of freedom within the chiral effective theory for spin-1 resonances

Karol Kampf, Jiri Novotny, Jaroslav Trnka

We study in detail various aspects of the renormalization of the spin-1 resonance propagator in the effective field theory framework. First, we briefly review the formalisms for th…
