Unparticle effects in neutrino telescopes

Abstract

Recently H.Georgi has introduced the concept of unparticles in order to describe the low energy physics of a nontrivial scale invariant sector of an effective theory. We investigate its physical effects on the neutrino flux to be detected in a kilometer cubic neutrino telescope such as IceCube. We study the effects, on different observables, of the survival neutrino flux after through the Earth and the regeneration originated in the neutral currents. We calculate the contribution of unparticle physics to the neutrino-nucleon interaction and, then, to the observables in order to evaluate detectable effects in IceCUbe. Our results are compared with the bounds obtained by other non-underground experiments. Finally, the results are presented as an exclusion plot in the relevant parameters of the new physics stuff.Comment: Accepted in Phys.Rev.

“…Furthermore, unparticle contributions to the neutrino-nucleon cross section and its influence on the neutrino flux expected in a neutrino telescope such as IceCube have been reported in Ref. [58].…”

“…Dubbed "unparticle physics" because of the non-intuitive phase space structure, its introduction has caused a flurry of research into modifications to known physics and post-TeV predictions. Accelerator phenomenology has been the main emphasis in the literature [3][4][5][6][7][8][9][10] [11,12], but astrophysical/cosmological [13][14][15][16][17][18] [19][20][21][22][23][24] [ [25][26][27], low to ultra-high neutrino phenomenology [28][29][30][31][32][33][34][35] and general quantum field theory [36][37][38][39][40][41] [42,43] applications have been of extreme importance as well.…”

“…There is considerably less literature dealing with bounds on the exotic quark masses [58,59], which in general depend on the masses of the heavy gauge bosons. From the search for supersymmetric particles at the Tevatron, a bound on the D quark mass of about 300 GeV was obtained for m Z ′ around 1 TeV [58].…”

“…From the search for supersymmetric particles at the Tevatron, a bound on the D quark mass of about 300 GeV was obtained for m Z ′ around 1 TeV [58]. Another constraint was obtained in [59] from the experimental data on the Z →bb decay and electroweak precision measurements at the Z pole: it was found that the T quark mass is bounded into the 1500-4000 GeV interval for m Y −− around 700 GeV.…”
