The transverse-momentum subtraction method at NLO applied to Higgs boson production at the LHC
We consider the extension of the transverse-momentum () subtraction
method at next-to-next-to-next-to-leading order (NLO) in perturbative QCD.
While all the -subtraction ingredients at are known in
analytical form, the third-order collinear functions and helicity-flip
functions, which contribute only at , are approximated using a
prescription which uses the known result for the total Higgs boson cross
section at this order. As a first application of the third-order
-subtraction method, we present the NLO rapidity distribution of the
Higgs boson at the LHC.Comment: 4 pages, 1 figure, contribution to the 2019 QCD session of the 54th

A Pátria aos quadrados: Joaquim de Vasconcelos (1849-1936) painéis identitários
Considered the founder of Art History in Portugal with a rigorous method, Joaquim de Vasconcelos was also a Musicologist, Museologist, Teacher and Professor, Art Critic and a "champion" of visual transmission “systems” like Photography and Drawing. His capacity for critical analysis, his anarchic enthusiasm for various areas of knowledge indicating right or wrong tracks when almost everything was still to be done, impose him as an anti-mythical and unique character who created his own legend, a myth and a romantic hero, a master of himself far beyond from Gottfried Semper (1803-1879) or Giambattista Cavalcaselle (1819-1897) just to point out two of the masters that he admired. Homeland squares is not only a way of referring how tiles are a very important part of the Portuguese identity puzzle, but also a way of alluding to the geometry of parallels and meridians that Joaquim de Vasconcelos drew when trying to identify the Art in Portugal.Considerado o fundador da HistĂłria da Arte em Portugal com um mĂ©todo rigoroso, Joaquim de Vasconcelos foi um MusicĂłlogo, MuseĂłlogo, Professor, CrĂtico de Arte e "campeĂŁo" dos sistemas de transmissĂŁo visual como a Fotografia e o Desenho. A sua capacidade de análise crĂtica, o entusiasmo anárquico por várias áreas do conhecimento indicando pistas certas, ou erradas, num tempo onde quase tudo estava ainda por escrever, impõe Vasconcelos como um caráter anti-mĂtico e Ăşnico, um homem que criou a sua prĂłpria lenda, um mito e um herĂłi romântico, um mestre de si mesmo muito alĂ©m de Gottfried Semper (1803-1879) ou Giambattista Cavalcaselle (1819-1897). apenas para apontar dois mestres que admirava. A Pátria aos quadrados expressa, em metáfora, como os azulejos sĂŁo uma parte muito significativa do quebra-cabeças da identidade portuguesa e alude igualmente Ă geometria dos paralelos e meridianos que Joaquim de Vasconcelos desenhou ao tentar identificar a Arte em Portugal
The stable subset of a univalent self-map
We give a complete description of the stable subset (the union of all
backward orbit with bounded step) and of the pre-models of a univalent self-map
, where is a Kobayashi hyperbolic cocompact complex manifold,
such as the ball or the polydisc in . The result is obtained studying the
complex structure of a decreasing intersection of complex manifolds, all
biholomorphic to
