Pomeron-Odderon interactions in a Reggeon field theory

2017-01-13T10:00:00-05:00

Author(s): Jochen Bartels, Carlos Contreras, and Gian Paolo Vacca
In this paper we extend our recent nonperturbative functional renormalization group analysis of Reggeon field theory to the interactions of Pomeron and Odderon fields. We establish the existence of a fixed point and its universal properties, which exhibits a novel symmetry structure in the space of …

Author(s): Stéphane Munier, Stéphane Peigné, and Elena Petreska
We derive the medium-induced, fully coherent soft gluon radiation spectrum associated with the hard forward scattering of an energetic parton off a nucleus, in the saturation formalism within the Gaussian approximation for the relevant correlators of Wilson lines and for finite number of colors.

Self-similar scalar field collapse

Author(s): Narayan Banerjee and Soumya Chakrabarti
A spherically symmetric collapsing scalar field model is discussed with a dissipative fluid which includes a heat flux. This vastly general matter distribution is analyzed at the expense of a high degree of symmetry in the space-time, that of conformal flatness and self-similarity. Indeed collapsing…

Constraints on the symmetry noninheriting scalar black hole hair

Author(s): Ivica Smolić
Any recipe to grow black hole hair has to circumvent no-hair theorems by violating some of their assumptions. Recently discovered hairy black hole solutions exist due to the fact that their scalar fields don’t inherit the symmetries of the spacetime metric. We present here a general analysis of the …

Author(s): Tetsutaro Higaki, Naoyuki Takeda, and Yusuke Yamada
The relaxion mechanism elegantly solves the Higgs hierarchy problem, but it requires that the early Universe experiences a long inflation phase with a small energy scale since the settle down of the relaxion needs to take place during inflation.

Do spikes persist in a quantum treatment of spacetime singularities?

Author(s): Ewa Czuchry, David Garfinkle, John R. Klauder, and Włodzimierz Piechocki
The classical approach to spacetime singularities leads to a simplified dynamics in which spatial derivatives become unimportant compared to time derivatives, and thus each spatial point essentially becomes uncoupled from its neighbors. This uncoupled dynamics leads to sharp features (called “spikes…

Author(s): V. Khachatryan et al. (CMS Collaboration)
An inclusive search for supersymmetry using razor variables is performed in events with four or more jets and no more than one lepton. The results are based on a sample of proton-proton collisions corresponding to an integrated luminosity of 2.3  fb^{−1} collected with the CMS experiment at a center…

Search for proton decay via p→e^{+} π^{0} and p→μ^{+} π^{0} in 0.31 megaton·years exposure of the Super-Kamiokande water Cherenkov detector

2017-01-06T10:00:00-05:00

Author(s): K. Abe et al. (Super-Kamiokande Collaboration)

Proton decay is not allowed in the Standard Model but is a signature prediction of Grand Unified Theories (GUTs). The Super-Kamiokande Collaboration reports results from its rigorous search for proton decay in two channels. The non-observation of proton decay sets new lower bounds on the proton lifetime and imposes stringent constraints on possible GUT and other Beyond the Standard Model scenarios.
