Non-local massive gravity
Abstract We present a general covariant action for massive gravity merging together a class of “non-polynomial” and super-renormalizable or finite theories of gravity with the non-local theory of gravity recently proposed by Jaccard, Maggiore and...

Aligned natural inflation: Monodromies of two axions
Abstract Natural (axionic) inflation [1] can accommodate sizeable primordial tensor modes but suffers from the necessity of trans-Planckian variations of the inflaton field. This problem can be solved via the mechanism of aligned axions [2], where...

Universal thermodynamics in different gravity theories: Modified entropy on the horizons
Abstract The paper deals with universal thermodynamics for FRW model of the universe bounded by apparent (or event) horizon. Assuming Hawking temperature on the horizon, the unified first law is examined on the horizon for different gravity...

Cosmic-ray neutrinos from the decay of long-lived particle and the recent IceCube result
Abstract Motivated by the recent IceCube result, we study high energy cosmic-ray neutrino flux from the decay of a long-lived particle. Because neutrinos are so transparent, high energy neutrinos produced in the past may also contribute to the...

On the renormalization group flow in two dimensional superconformal models
Abstract We extend the results on the RG flow in the next to leading order to the case of the supersymmetric minimal models SM ...

Massive twistor particle with spin generated by Souriau–Wess–Zumino term and its quantization
Abstract We present a new model of D = 4 relativistic massive particle with spin and we describe its quantization. The model is obtained by an extension...

Ricci-flat spacetimes with l-conformal Galilei symmetry
Abstract Ricci-flat metrics of the ultrahyperbolic signature which enjoy the l-conformal Galilei symmetry are constructed. They involve the AdS ...

The electroweak vacuum angle
Abstract We reveal a new source of CP-violation in the electroweak sector that is free of any experimental bounds, and we highlight the possible implications for baryogenesis.

Mimic the optical conductivity in disordered solids via gauge/gravity duality
Abstract We study the optical conductivity in a ( 2 + 1 ) -dimensional non-relativistic field theory...

Upgrade of LHCb-RICH detectors
Abstract The two RICH detectors installed in LHCb have performed successfully during the 2010–2012 data taking period. The data from these detectors were essential to most of the physics results published by LHCb. During this period LHCb collected...

Kac–Moody symmetries of IIB supergravity
Abstract We formulate the bosonic sector of IIB supergravity as a non-linear realisation. We show that this non-linear realisation contains the Borel subalgebras of SL(11) and E 7 and argue that it can be enlarged so as to be...

Sudakov effects in BBNS approach
Abstract The end-point singularity is an unsolved problem in BBNS approach. Incorporating the partonic transverse momentum and the Sudakov form factor, this problem can be solved model-independently. We discuss the Sudakov effects in BBNS approach....

Rare top decays t→cγ, t→cg and CKM unitarity
Abstract Top flavour-changing neutral decays are extremely suppressed within the Standard Model (SM) by the GIM mechanism, but can reach observable rates in some of its extensions. We compute the branching ratios for t→cγ and t→cg in minimal SM...
