In this short note, we present a refinement of the logarithmic-geometric mean inequality. As an application of our result, we obtain an operator inequality associated with geometric and logarithmic means.
We show, using the tunneling method, that Lovelock black holes Hawking radiate with a perfect blackbody spectrum. This is a new result. Within the semiclassical (WKB) approximation the temperature of the spectrum is given by the semiclassical Hawking temperature. Beyond the semiclassical approximation the thermal nature of the spectrum does not change but the temperature undergoes some higher o...
We present predictions for the gluon-fusion Higgs $p_T$ spectrum at third resummed and fixed order (N$^3$LL$'+$N$^3$LO) including fiducial cuts as required by experimental measurements Large Hadron Collider. Integrating spectrum, we predict first time total cross section to (N$^3$LO) improved resummation. The N$^3$LO correction is enhanced cut-induced logarithmic effects not reproduced inclusiv...
A bstract We point out some common qualitative features of the Coon amplitude — a family deformations Veneziano with logarithmic Regge trajectories and open string scattering for strings ending on D-brane in AdS. Both reduce to at relatively low energies. systems have an accumulation their spectrum, infinite number states below certain energy. The approach this is very similar. same high-energy...
The origin of the knee in the energy spectrum of cosmic rays is an outstanding problem in astroparticle physics. Numerous mechanisms have been proposed to explain the structure in the all-particle spectrum. In the article basic ideas of several models are summarized, including diffusive acceleration of cosmic rays in shock fronts, acceleration via cannonballs, leakage from the Galaxy, interacti...
We study the constraints that the operator product expansion imposes on large Nc inspired QCD models for current-current correlators. We focus on the constraints obtained by going beyond the leading-order parton computation. We explicitly show that, assumed a given mass spectrum: linear Regge behavior in n (the principal quantum number) plus corrections in 1/n, we can obtain the logarithmic (an...
