Search for long-lived heavy neutral leptons with displaced vertices in proton-proton collisions at √s= 13 TeV
A search for heavy neutral leptons (HNLs), the right-handed Dirac or Majorana neutrinos, is performed in final states with three charged leptons (electrons or muons) using proton-proton collision data collected by the CMS experiment at √s= 13 TeV at the CE ...
2022Dirac Group(oid)s and Their Homogeneous Spaces
A theorem of Drinfel'd (Drinfel'd (1993)) classifies the Poisson homogeneous spaces of a Poisson Lie group (G,πG) via a special class of Lagrangian subalgebras of the Drinfel'd double of its Lie bialgebra. This result is extended in Liu et al. (1998) to a ...
EPFL2011Dirac Lie Groups, Dirac Homogeneous Spaces and the Theorem of Drinfeld
The notions of Poisson Lie group and Poisson homogeneous space are extended to the Dirac category. The theorem of Drinfeld on the one-to-one correspondence between Poisson homogeneous spaces of a Poisson Lie group and a special class of Lagrangian subalgeb ...
2011Initial state radiation in Majorana Dark Matter annihilations
The cross section for a Majorana Dark Matter particle annihilating into light fermions is helicity suppressed. We show that, if the Dark Matter is the neutral Majorana component of a multiplet which is charged under the electroweak interactions of the Stan ...
2011Bounds in 4D conformal field theories with global symmetry
Riccardo Rattazzi, Alessandro Vichi
We explore the constraining power of OPE associativity in 4D conformal field theory with a continuous global symmetry group. We give a general analysis of crossing symmetry constraints in the 4-point function , where phi is ...
