Neutrinoless double beta decay: searching for new physics with comparison of different nuclei
A. Ali, A. V. Borisov, D. V. Zhuridov
The neutrinoless double beta decay is analyzed using a general Lorentz invariant effective Lagrangian for various decaying nuclei of current experimental interest: Ge, $^{82…
Detecting the Higgs boson(s) in LambdaSUSY
Enrico Bertuzzo, Marco Farina
We reconsider the Higgs bosons discovery potential in the LambdaSUSY framework, in which the masses of the scalar particles are increased already at tree level via a largish supers…
Implications of the 125 GeV Higgs boson for scalar dark matter and for the CMSSM phenomenology
M. Kadastik, K. Kannike, A. Racioppi +1
We study phenomenological implications of the ATLAS and CMS hint of a GeV Higgs boson for the singlet, and singlet plus doublet non-supersymmetric dark matter models, an…
Symmetryless Dark Matter
Yuji Kajiyama, Kristjan Kannike, Martti Raidal
It is appealing to stabilize dark matter by the same discrete symmetry that is used to explain the structure of quark and lepton mass matrices. However, to generate the observed fe…
Anthropic solution to the magnetic muon anomaly: the charged see-saw
Kristjan Kannike, Martti Raidal, David M. Straub +1
We present models of new physics that can explain the muon g-2 anomaly in accord with with the assumption that the only scalar existing at the weak scale is the Higgs, as suggested…
Model-independent constraints on new physics in b --> s transitions
Wolfgang Altmannshofer, Paride Paradisi, David M. Straub
We provide a comprehensive model-independent analysis of rare decays involving the b --> s transition to put constraints on dimension-six Delta(F)=1 effective operators. The constr…
U(2) and MFV in Supersymmetry
David M. Straub
A suitably broken U(2)^3 symmetry acting on the first two generations of quarks and squarks is studied as a natural generalization of the Minimal Flavour Violation principle to the…
B-decay CP-asymmetries in SUSY with a U(2)^3 flavour symmetry
Riccardo Barbieri, Paolo Campli, Gino Isidori +2
We study CP asymmetries in rare B decays within supersymmetry with a U(2)^3 flavour symmetry, motivated by the SUSY flavour and CP problems, the hierarchies in the Yukawa couplings…
Freed Leptogenesis
Dmitry V. Zhuridov
Economical extensions of the Standard Model (SM), in which the famous Davidson-Ibarra bound on the CP asymmetry relevant for leptogenesis may be significantly relaxed by the loop e…
Can CoGeNT and DAMA Modulations Be Due to Dark Matter?
Marco Farina, Duccio Pappadopulo, Alessandro Strumia +1
We explore the dark matter interpretation of the anomalies claimed by the DAMA and CoGeNT experiments, in conjunction with the various null direct-detection experiments. An indepen…
Towards leptogenesis at NLO: the right-handed neutrino interaction rate
Alberto Salvio, Paolo Lodone, Alessandro Strumia
We compute quantum and thermal corrections to the right-handed neutrino interaction rate in the early universe at next-to-leading order in all the relevant SM couplings (gauge, top…
Higgs boson signals in lambda-SUSY with a Scale Invariant Superpotential
Enrico Bertuzzo, Marco Farina
We reconsider the lambda-SUSY model, in which the mass of the Higgs boson is raised already at tree level up to about 200 GeV via an additional interaction in the superpotential be…
Direct detection and CMB constraints on light DM scenario of top quark asymmetry and dijet excess at Tevatron
Andi Hektor, Gert Hütsi, Mario Kadastik +3
We study in detail the model by Isidori and Kamenik that is claimed to explain the top quark forward-backward asymmetry at Tevatron, provide GeV-scale dark matter (DM), and possibl…
Supersymmetry without a light Higgs boson but with a light pseudoscalar
Paolo Lodone
We consider the lambda-SUSY model, a version of the NMSSM with large lambda H_1 H_2 S coupling, relaxing the approximation of large singlet mass and negligible mixing of the scalar…
New Solution for Neutrino Masses and Leptogenesis in Adjoint SU(5)
Kristjan Kannike, Dmitry Zhuridov
We investigate baryogenesis via leptogenesis and generation of neutrino masses and mixings through the Type I plus Type III seesaw plus an one-loop mechanism in the context of Reno…
Distance Between Quantum Field Theories As A Measure Of Lorentz Violation
Damiano Anselmi, Dario Buttazzo
We study the distance between symmetry-violating quantum field theories and the surface of symmetric theories. We use this notion to quantify how precise Lorentz symmetry is today,…
U(2) and Minimal Flavour Violation in Supersymmetry
Riccardo Barbieri, Gino Isidori, Joel Jones-Perez +2
Rather than sticking to the full approximate symmetry normally invoked in Minimal Flavour Violation, we analyze the consequences on the current flavour data of a suitably…
Implications of XENON100 and LHC results for Dark Matter models
Marco Farina, Mario Kadastik, Martti Raidal +3
We perform a fit to the recent Xenon100 data and study its implications for Dark Matter scenarios. We find that Inelastic Dark Matter is disfavoured as an explana- tion to the DAMA…
CP Violation in Supersymmetry with Effective Minimal Flavour Violation
Riccardo Barbieri, Paolo Lodone, David M. Straub
We analyze CP violation in supersymmetry with Effective Minimal Flavour Violation, as recently proposed in arXiv:1011.0730. Unlike the case of standard Minimal Flavour Violation, w…
LHC bounds on large extra dimensions
Roberto Franceschini, Gian Francesco Giudice, Pier Paolo Giardino +2
We derive new dominant bounds on the coefficient of the effective operator generated by tree-level graviton exchange in large extra dimensions from pp \rightarrow jj data at LHC: M…
