Review of Particle Physics

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summa ...

Mildly sequestered supergravity models and their realization in string theory

Claudio Scrucca, Christopher John Andrey

We elaborate on the idea that five-dimensional models where sequestering is spoiled due to contact interactions induced by vector multiplets may still be mildly sequestered if a global version of the gauge symmetry associated to the latter survives in the ...

A non standard supersymmetric spectrum

Enrico Bertuzzo, Duccio Pappadopulo, Paolo Lodone

Taking a bottom-up point of view and focussing on the lack of signals so far in the Higgs and in the flavour sectors, we argue in favour of giving consideration to supersymmetric extensions of the Standard Model where the lightest Higgs boson has a mass be ...

Globally and locally supersymmetric effective theories for light fields

Claudio Scrucca, Leonardo Brizi

We reconsider the general question of how to characterize most efficiently the low-energy effective theory obtained by integrating out heavy modes in globally and locally supersymmetric theories. We consider theories with chiral and vector multiplets and i ...

Olivier Schneider, Pierre Vogel, Greig Alan Cowan, Jian Liu

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2778 new measurements from 645 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summa ...

Natural mu and B mu in gauge mediation

Riccardo Rattazzi

We propose a natural solution to the mu problem in gauge mediation. It relies on the logarithmic dependence of the effective Kahler potential on the messenger threshold superfield X. Thus, mu and B mu naturally arise at one and two loops, respectively. Mor ...

Living dangerously with low-energy supersymmetry

Riccardo Rattazzi

We stress that the lack of direct evidence for supersymmetry forces the soft mass parameters to lie very close to the critical line separating the broken and unbroken phases of the electroweak gauge symmetry. We argue that the level of criticality, or fine ...

Gravitational quantum corrections in warped supersymmetric brane worlds

Riccardo Rattazzi, Claudio Scrucca

We study gravitational quantum corrections in supersymmetric theories with warped extra dimensions. We develop for this a superfield formalism for linearized gauged supergravity. We show that the 1-loop effective Kahler potential is a simple functional of ...

Electroweak symmetry breaking after LEP1 and LEP2

Riccardo Rattazzi

In a generic "universal" theory of electroweak symmetry breaking, simple symmetry considerations and absence of tuning imply that heavy new physics affects the low-energy data through four parameters. These include and properly extend the generally insuffi ...
