Complete One-Loop MSSM Predictions for B --> lepton lepton' at the Tevatron and LHC
Athanasios Dedes, Janusz Rosiek, Philip Tanedo
During the last few years the Tevatron has dramatically improved the bounds on rare B-meson decays into two leptons. In the case of B_s --> mu+ mu-, the current bound is only ten t…
Effective action of a five-dimensional domain wall
Y. Burnier, K. Zuleta
We calculate the four-dimensional low-energy effective action for the perturbations of a two-scalar domain wall model in five dimensions. Comparison of the effective action to the…
Computing the Newton polygon of the implicit equation
Ioannis Z. Emiris, Christos Konaxis, Leonidas Palios
We consider polynomially and rationally parameterized curves, where the polynomials in the parameterization have fixed supports and generic coefficients. We apply sparse (or toric)…
Bright High z SnIa: A Challenge for LCDM?
L. Perivolaropoulos, A. Shafieloo
It has recently been pointed out by Kowalski et. al. (arxiv:0804.4142) that there is `an unexpected brightness of the SnIa data at z>1'. We quantify this statement by constructing…
Halo Density Profiles Consistent with Asymmetric M-B Velocity Distributions-Implications on Direct Dark Matter Searches
J. D. Vergados
In the present paper we obtain the WIMP velocity distribution in our vicinity starting from spherically symmetric WIMP density profiles in a self consistent way by employing the Ed…
Line shape of the muH(3p - 1s) hyperfine transitions
D. S. Covita, D. F. Anagnostopoulos, H. Gorke +13
The (3p - 1s) X-ray transition to the muonic hydrogen ground state was measured with a high resolution crystal spectrometer. A Doppler effect broadening of the X-ray line was estab…
Spinor-Vector Duality in Heterotic SUSY Vacua
Tristan Catelin-Jullien, Alon E. Faraggi, Costas Kounnas +1
We elaborate on the recently discovered spinor-vector duality in realistic free fermionic heterotic vacua. We emphasize the interpretation of the freely-acting orbifolds carried ou…
A novel large-volume Spherical Detector with Proportional Amplification read-out
I. Giomataris, I. Irastorza, I. Savvidis +11
A new type of radiation detector based on a spherical geometry is presented. The detector consists of a large spherical gas volume with a central electrode forming a radial electri…
Measuring co-authorship and networking-adjusted scientific impact
John P. A. Ioannidis
Appraisal of the scientific impact of researchers, teams and institutions with productivity and citation metrics has major repercussions. Funding and promotion of individuals and s…
Searching for Nambu-Goldstone Bosons at the LHC
Athanasios Dedes, Terrance Figy, Stefan Hoche +2
Phenomenological implications of a minimal extension to the Standard Model are considered, in which a Nambu-Goldstone boson emerges from the spontaneous breaking of a global U(1) s…
Quantum chaos in disordered graphene
I. Amanatidis, S. N. Evangelou
We have studied numerically the statistics for electronic states (level-spacings and participation ratios) from disordered graphene of finite size, described by the aspect ratio $W…
A probabilistic key agreement scheme for sensor networks without key predistribution
V. Liagkou, E. Makri, P. Spirakis +1
The dynamic establishment of shared information (e.g. secret key) between two entities is particularly important in networks with no pre-determined structure such as wireless senso…
Minimal graphs in with bounded Jacobians
Th. Hasanis, A. Savas-Halilaj, Th. Vlachos
We obtain a Bernstein type result for entire two dimensional minimal graphs in , which extends a previous one due to L. Ni. Moreover, we provide a characterization…
Can Solar Neutrinos be a Serious Background in Direct Dark Matter Searches?
J. D. Vergados, H. Ejiri
The coherent contribution of all neutrons in neutrino nucleus scattering due to the neutral current is examined considering the boron solar neutrinos. These neutrinos could potenti…
Testing GRBs as Standard Candles
S. Basilakos, L. Perivolaropoulos
Several correlations among Gamma Ray Burst (GRB) observables with available redshifts have been recently identified. Proper evaluation and calibration of these correlations may fac…
Is the CMB shift parameter connected with the growth of cosmological perturbations?
S. Basilakos, S. Nesseris, L. Perivolaropoulos
We verify numerically that in the context of general relativity (GR), flat models which have the same and CMB shift parameter but different and also h…
A U(3)_C X U(3)_L X U(3)_R gauge symmetry from intersecting D-branes
G. K. Leontaris
A three-family non-supersymmetric model with U(3)^3 gauge symmetry is analyzed in the context of intersecting D-branes. This is equivalent to the `trinification' model extended by…
Vacuum Energy, the Cosmological Constant and Compact Extra Dimensions: Constraints from Casimir Effect Experiments
Leandros Perivolaropoulos
We consider a universe with a compact extra dimension and a cosmological constant emerging from a suitable ultraviolet cutoff on the zero point energy of the vacuum. We derive the…
Black Holes at the LHC
Panagiota Kanti
In these two lectures, we will address the topic of the creation of small black holes during particle collisions in a ground-based accelerator, such as LHC, in the context of a hig…
Bulk emission of scalars by a rotating black hole
M. Casals, S. R. Dolan, P. Kanti +1
We study in detail the scalar-field Hawking radiation emitted into the bulk by a higher-dimensional, rotating black hole. We numerically compute the angular eigenvalues, and solve…
