The boson mass spectrum of the electroweak SU (4)L⊗ U (1)Ymodel with exotic electric charges is investigated by using the algebraical approach supplied by the method of solving gauge models with high symmetries. Our approach predicts for the boson sector a one-parameter mass scale to be tuned in order to match the data obtained at LHC, LEP, CDF.

A consistent quantum treatment of general gauge theories with an arbitrary gauge-fixing in the presence of soft breaking of the BRST symmetry in the field–antifield formalism is developed. It is based on a gauged (involving a field-dependent parameter) version of finite BRST transformations. The prescription allows one to restore the gauge-independence of the effective action at its extremals and therefore also that of the conventional S-matrix for a theory with BRST-breaking terms being additively introduced into a BRST-invariant action in order to achieve a consistency of the functional integral. We demonstrate the applicability of this prescription within the approach of functional renormalization group to the Yang–Mills and gravity theories. The Gribov–Zwanziger action and the refined Gribov–Zwanziger action for a many-parameter family of gauges, including the Coulomb, axial and covariant gauges, are derived perturbatively on the basis of finite gauged BRST transformations starting from Landau gauge. It is proved that gauge theories with soft breaking of BRST symmetry can be made consistent if the transformed BRST-breaking terms satisfy the same soft BRST symmetry breaking condition in the resulting gauge as the untransformed ones in the initial gauge, and also without this requirement.

To speak of Brahms and Beethoven in the same breath is almost a cliché: Brahms was intimately conscious of Beethoven's music from early youth. This article describes the details of his youthful involvement, the compositions he had in his repertoire as well as those other works which had a powerful effect on his development. By age 20, Brahms was frequently compared to Beethoven by people who met him or heard him play. My interest is in the way he was influenced by Beethoven and the manner in which he eventually found his own voice. The compositional history of his First Symphony provides the primary focus: its long gestation, and the alleged quote by Brahms given in Max Kalbeck's massive biography: ‘I'll never write a symphony, you have no idea what it feels like … to hear the footsteps of a giant behind one’. The reference is presumably to Beethoven, but there exists no corroborating evidence that Brahms ever said those words. They gained credence as one writer after another simply accepted Kalbeck's word. Yet substantial evidence exists that in writing his biography, Kalbeck distorted and even invented ‘facts’ when it suited his purposes, including a specific instance dealing with writing a symphony. An alternative view of the symphony's long gestation is based on a view of Brahms's compositional history. He wrote for musical forces he knew at first hand, and only from 1872 to 1875 did he have command of an orchestra. Intriguingly, while fulfilling the contemporary accepted demands of a symphony after Beethoven, Brahms devised an unusual strategy for the final movement, the basis of its great success.

This article combines critical, cultural, and musical analysis to situate Frozen: The Broadway Musical as a distinct work within Disney’s wider franchise. In this article, I consider the evolution of Elsa’s character on stage and the role of additional songs in the Frozen score. In so doing, I demonstrate how the stage adaptation distances itself from the feminist potential in the original animation. Using the lenses of palatability and gendered shame, I argue that Frozen: The Broadway Musical forces patriarchal modes of behaviour onto its heroines.

Although refuted for a long time as a monstrosity, today’s concepts in elementary particle physics necessitate it on theoretical grounds: The existence of isolated elementary magnetic north- or south poles. If compared with a proton, the mass of such a monopole is estimated to be gigantic; comparable to that of an amoeba. Under the impact of the empirical success of unified gauge models, the search for monopoles has been steadily enforced with the aid of new detection methods.
