How to find neutral leptons of the nuMSM?

An extension of the Standard Model by three singlet fermions with masses smaller than the electroweak scale allows to explain simultaneously neutrino oscillations, dark matter and baryon asymmetry of the Universe. We discuss the properties of neutral lepto ...

Non-perturbative processes with Fermion number non-conservation in different models of particle physics

Yannis Burnier

When a classical conservation law is broken by quantum corrections, the associated symmetry is said to be anomalous. This type of symmetry breaking can lead to interesting physics. For instance in strong interactions, the anomaly in the chiral current is i ...

Can an odd number of fermions be created due to chiral anomaly?

Yannis Burnier

We describe a possible creation of an odd number of fractionally charged fermions in the 1+1 dimensional Abelian Higgs model. We point out that for 1+1 dimensions this process does not violate any symmetries of the theory, nor makes it mathematically incon ...

Time-dependent CP-violating asymmetries in b→sq q transitions

Olivier Schneider, Aurelio Bay, Mingkui Wang, Chao Wang, Tagir Aushev, Lei Zhang, Sun Hee Kim, Sanjeev Kumar, Jing Li

We present new measurements of CP-violation parameters in B0→K0, K+K-KS0, f0(980)KS0, η′KS0, ωKS0, and KS0π0 decays based on a sample of 275×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. ...

Brane-worlds and theta-vacua

Reductions from odd to even dimensionalities (5 → 4 or 3 → 2), for which the effective low-energy theory contains chiral fermions, present us with a mismatch between ultraviolet and infrared anomalies. This applies to both local (gauge) and global currents ...

A medium size NEMP radiation system used in a shielded room

Michel Ianoz, Pierre Zweiacker

A bounded wave transmission line ENP simulator which achieves a very good confinement of the field inside its volume is described. Results of field mapping in free space and inside a shielded room are presented. These measurements have shown that the field ...

SPHALERONS AND AXION DYNAMICS IN HIGH TEMPERATURE QCD

We consider the effects of sphaleronlike transitions in the high-temperature QCD plasma. Because of the chiral anomaly, these imply rapid chirality change, and strongly influence the dynamics of any axionic fields that may couple to the topological winding ...

Tests of QCD from Jets on the Z0 Peak

Riccardo Rattazzi

We present a QCD analysis of some recently published data on jet production in Z0 decays. We find that the Z0 energy one can analyse also jet shape variables which were disregarded at lower energy e+e- experiments because of their large hadronization sensi ...

DETERMINATION OF g (omega rho pi) CONSTANT FROM QCD SUM RULES

The ωρπ coupling constant is calculated using a modified form of sum rules for the vertex function 〈0|T(Jμ(x), Jν(0))|π〉 accounting for the axial anomaly. The result gωρπ=16 GeV-1 is in good agreement with the estimates of the Vector Meson Dominance model. ...
