Review of Particle Physics, Particle Data Group

Olivier Schneider, Pierre Vogel, Greig Alan Cowan, Christophe Bauer

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2658 new measurements from 644 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We summarize ...

Cecotti-Fendley-Intriligator-Vafa index in a box

Alexander Monin

The Cecotti-Fendley-Intriligator-Vafa (CFIV) index in two-dimensional N = (2,2) models is revisited. We address the problem of "elementary" (nontopological) excitations over a kink solution, in the one-kink sector (using the Wess-Zumino or Landau-Ginzburg ...

One-loop adjoint masses for non-supersymmetric intersecting branes

Alessandro Vichi

We consider breaking of supersymmetry in intersecting D-brane configurations by slight deviation of the angles from their supersymmetric values. We compute the masses generated by radiative corrections for the ad joint scalars on the brane world-volumes. I ...

The lightest scalar in theories with broken supersymmetry

Claudio Scrucca, Leonardo Brizi

We study the scalar mass matrix of general supersymmetric theories with local gauge symmetries, and derive an absolute upper bound on the lightest scalar mass. This bound can be saturated by suitably tuning the superpotential, and its positivity therefore ...

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 ...

Effects of heavy modes on vacuum stability in supersymmetric theories

Claudio Scrucca, Leonardo Brizi

We study the effects induced by heavy fields on the masses of light fields in supersymmetric theories, under the assumption that the heavy mass scale is much higher than the supersymmetry breaking scale. We show that the square-masses of light scalar field ...

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 ...

Leptogenesis with TeV Scale Inverse Seesaw in SO(10)

Steve Blanchet

We discuss leptogenesis within a TeV-scale inverse seesaw model for neutrino masses where the seesaw structure is guaranteed by an SO(10) symmetry. Contrary to the TeV-scale type-I gauged seesaw, the constraints imposed by successful leptogenesis in these ...

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 ...
