Naturalness constraints on gauge-mediated supersymmetry breaking models

Gautam Bhattacharyya, Andrea Romanino

The question of naturalness is addressed in the context of gauge-mediated supersymmetry breaking models. Requiring that $M_{Z}$ arises naturally imposes upper limits on the right-han…

Naturalness bounds on gauge mediated soft terms

Paolo Ciafaloni, Alessandro Strumia

After a general discussion about the quantitative meaning of the naturalness upper bounds on the masses of supersymmetric particles, we compute these bounds in models with gauge-me…

Electric dipole moments from Yukawa phases in supersymmetric theories

Andrea Romanino, Alessandro Strumia

We study quark and electron EDMs generated by Yukawa couplings in supersymmetric models with different gauge groups, using the EDM properties under flavour transformations. In the…

Unified Theories with U(2) Flavor Symmetry

R. Barbieri, L. J. Hall, S. Raby +1

A general operator expansion is presented for quark and lepton mass matrices in unified theories based on a U(2) flavor symmetry, with breaking parameter of order $V_{cb} \approx m…

NLO Quarkonium Production in Hadronic Collisions

M. L. Mangano, A. Petrelli

We present some preliminary results on the next-to-leading order calculation in QCD of quarkonium production cross sections in hadronic collisions. We will show that the NLO total…

Radiatively induced light right-handed stop

Alessandro Strumia

A right-handed stop not much heavier or even lighter than the Z boson has today desirable phenomenological consequences. We study how it can result within the usual radiative scena…

$R$ -parity-Violating Supersymmetric Yukawa Couplings: A Mini-review

Gautam Bhattacharyya

I review the bounds on the $R$ -parity-violating supersymmetric Yukawa couplings from the considerations of proton stability, $n$ -- $n ˉ$ oscillation, $ν_{e}$ -Majorana mass, neutri…

A Non-supersymmetric Interpretation of the CDF e+e-γγ+ missing E_T Event

Gautam Bhattacharyya, Rabindra N. Mohapatra

The $\eegg$ event reported recently by the CDF Collaboration has been interpreted as a signal of supersymmetry in several recent papers. In this article, we report on an alternativ…

On axion-mediated macroscopic forces again

R. Barbieri, A. Romanino, A. Strumia

In a supersymmetric unified theory or in a generic model where a large neutron electric dipole moment $d_{N}$ is expected, close to the present bound, we estimate the relation g_aNN…

Electric dipole moments in supersymmetric theories

Andrea Romanino

Intrinsic EDMs in microscopic systems at a level of sensitivity achievable in experiments under way or foreseen are predicted in supersymmetric unified theories. I describe this an…

Charge and color breaking minima and constraints on the MSSM parameters

A. Strumia

The MSSM potential can have unphysical minima deeper than the physically acceptable one. We point out that their presence is quite generic in SO(10) unification with supergravity m…

Colour-octet NLO QCD corrections to hadronic $χ_{J}$ decays

Andrea Petrelli

In this paper we present a complete next-to-leading order QCD calculation of the $χ_{J}$ ( $^{3} P_{J}; J = 0, 1, 2$ ) hadronic decay width. We include the NLO colour-octet contribution, as d…
