We study effective dynamics of the nonsupersymmetric two-dimensional CP(N-1) model in the large
N limit. This model is deformed by a mass term m preserving Z_N symmetry of the Lagrangian. At small m
the theory is strongly coupled and resembles the undeformed CP(N-1) model, while at large m it is in a
weakly coupled Higgs phase with spontaneously broken Z_N.We ...

It has been shown that non-Abelian solitonic vortex strings supported in four-dimensional (4D)
N = 2 supersymmetric QCD (SQCD) with the U(2) gauge group and N_f =4 quark flavors behave
as critical superstrings. In addition to four translational moduli, the non-Abelian strings under
consideration carry six orientational and size moduli. Together they form a ten-dimensional space
required for a superstring to ...

It has been shown that non-Abelian vortex string supported in four-dimensional (4D) N =2
supersymmetric QCD (SQCD) with the U(2) gauge group and N_f =4 quark flavors becomes a critical
superstring. This string propagates in the ten-dimensional space formed by a product of the flat 4D space
and an internal space given by a Calabi-Yau noncompact threefold, namely, ...

We present first evidence that the cosine of the CP-violating weak phase 2β is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of B0→D(∗)h0 with D→KS0π+π- decays, where h0 {π0,η,ω} denotes a light unflavored and neutral hadron. The measurement is performed combining the final ...

Combined ATLAS and CMS measurements of the Higgs boson production and decay rates, as well as constraints on its couplings to vector bosons and fermions, are presented. The combination is based on the analysis of five production processes, namely gluon fusion, vector boson fusion, and associated production with a W or a Z boson or ...

We study the integral Bailey lemma associated with the A_n-root system and
identities for elliptic hypergeometric integrals generated thereby. Interpreting integrals as
superconformal indices of four-dimensional N = 1 quiver gauge theories with the gauge
groups being products of SU(n + 1), we provide evidence for various new dualities. Further
con rmation is achieved by explicitly checking that the ...

We show that equivariant Donaldson polynomials of compact toric surfaces can be calculated as residues of suitable combinations of Virasoro conformal blocks, by building on AGT correspondence between N=2 supersymmetric gauge theories and two-dimensional conformal field theory.Talk. 1 1 http://salafrancesco.altervista.org/wugo2015/tanzini.pdf. presented by A.T. at the conference Interactions between Geometry and Physics - in honor of ...

Smooth <img />-supermanifolds have been introduced and studied recently. The corresponding sign rule is given by the ‘scalar product’ of the involved <img />-degrees. It exhibits interesting changes in comparison with the sign rule using the parity of the total degree. With the new rule, nonzero degree even coordinates are not nilpotent, and even (resp., odd) coordinates ...

The polarizations of the ϒ(1S), ϒ(2S), and ϒ(3S) mesons are measured as a function of the charged particle multiplicity in proton–proton collisions at <img />. The measurements are performed with a dimuon data sample collected in 2011 by the CMS experiment, corresponding to an integrated luminosity of 4.9 fb−1. The results are extracted from the dimuon decay angular distributions, in two ranges of ϒ(nS)transverse momentum ...

A search is performed for a new resonance decaying into a lighter resonance and a Z boson. Two channels are studied, targeting the decay of the lighter resonance into either a pair of oppositely charged τ leptons or a <img /> pair. The Z boson is identified via its decays to electrons or muons. The search exploits data ...

A recently proposed correspondence between 4-dimensional N=2 SUSY SU(k) gauge theories on R^4/Z_m and SU(k) Toda-like theories with Z_m parafermionic symmetry is used to construct four-point N=1 super Liouville conformal block, which corresponds to the particular case k=m=2.
The construction is based on the conjectural relation between moduli spaces of SU(2) instantons on R^4/Z_2 and algebras ...
