Spontaneous SUSY breaking in various dimensions
Abstract We generalize the ISS model of spontaneous supersymmetry breaking to lower dimensions. We also comment on the dynamics of the corresponding brane systems in string theory, and on possible applications to gauge/gravity duality. ...

(Non)-supersymmetric marginal deformations from twistor string theory
Abstract The tree-level amplitudes in the β-deformed supersymmetric gauge theory are derived from twistor string theory. We first show that a simple generalization of [M. Kulaxizi, K. Zoubos, Marginal deformations of N ...

Heterotic twistor–string theory
Abstract We reformulate twistor–string theory as a heterotic string based on a twisted ( 0 , 2 ) model....

Phenomenological consequences of four zero neutrino Yukawa textures
Abstract For type I seesaw and in the basis where the charged lepton and heavy right-handed neutrino mass matrices are real and diagonal, four has been shown to be the maximum number of zeros allowed in the neutrino Yukawa coupling matrix ...

Geometric metastability, quivers and holography
Abstract We use large N duality to study brane/antibrane configurations on a class of Calabi–Yau manifolds. With only branes present, the Calabi–Yau manifolds in question give rise to N = ...

Use of transverse polarization to probe R-parity violating supersymmetry at ILC
Abstract In supersymmetric theories with R-parity violation, squarks and sleptons can mediate Standard Model fermion–fermion scattering processes. These scalar exchanges in e ...

In-medium hadronization in the deconfined matter at RHIC and LHC
Abstract We study the mechanism and probability of in-medium hadronization in the deconfined medium produced in heavy-ion collisions at RHIC and LHC. We show the likelihood of color-neutral objects to be formed inside the partonic fireball and the...

Quasinormal resonances of near-extremal Kerr–Newman black holes
Abstract We study analytically the fundamental resonances of near-extremal, slowly rotating Kerr–Newman black holes. We find a simple analytic expression for these black-hole quasinormal frequencies in terms of the black-hole physical parameters: ...

Light dark matter in the singlet-extended MSSM
Abstract We discuss the possibility of light dark matter in a general singlet extension of the MSSM. Singlino LSPs with masses of a few GeV can explain the signals reported by the CRESST, CoGeNT and possibly also DAMA experiments. The interactions...

Coherent and squeezed states in black-hole evaporation
Abstract In earlier Letters, we adopted a complex approach to quantum processes in the formation and evaporation of black holes. Taking Feynman's + i ε ...

Degenerate minimal see-saw and leptogenesis
Abstract We analyze the most general version of the supersymmetric minimal see-saw model with only two right-chiral neutrinos which are degenerate in masses at the scale of Grand Unification. We study the renormalization effects that give rise to...

Cooper–Frye formula and non-extensive coalescence at RHIC energy

Hadron optics: Diffraction patterns in deeply virtual Compton scattering
Abstract We show that the Fourier transform of the deeply virtual Compton scattering (DVCS) amplitude with respect to the skewness variable ζ at fixed invariant momentum transfer squared t provides a unique way to visualize the structure of the...

Tunneling across dilaton coupled black holes in anti de Sitter spacetime
Abstract Considering generalised action for dilaton coupled Maxwell–Einstein theory in four dimensions, Gao and Zhang obtained black holes solutions for asymptotically anti de Sitter (Ads) and de Sitter (ds) spacetimes. We study the Hawking...

Quantum scale invariance, cosmological constant and hierarchy problem
Abstract We construct a class of theories which are scale-invariant on quantum level in all orders of perturbation theory. In a subclass of these models scale invariance is spontaneously broken, leading to the existence of a massless dilaton. The...

Gravity on a multifractal
Abstract Despite their diversity, many of the most prominent candidate theories of quantum gravity share the property to be effectively lower-dimensional at small scales. In particular, dimension two plays a fundamental role in the finiteness of...
