Unique neutrino mass operator at any mass dimension [PDF]
Physics Letters B, 2011 When the standard model is viewed as a low energy effective theory, the neutrinos can obtain mass from higher dimensional operators. It has been known for long that such an operator first appears at mass dimension five and that it is unique. Here we show that the effective neutrino mass operator at every higher dimension is unique.

The two-mass contribution to the three-loop pure singlet operator matrix element [PDF]
Nuclear Physics B, 2018 We present the two-mass QCD contributions to the pure singlet operator matrix element at three loop order in x-space. These terms are relevant for calculating the structure function F2(x,Q2) at O(αs3) as well as for the matching relations in the variable

Mass operator in the light-cone representation [PDF]
Physical Review D, 1999 I argue that for the case of fermions with nonzero bare mass there is a term in the matter density operator in the light-cone representation which has been omitted from previous calculations. The new term provides agreement with previous results in the equal-time representation for mass perturbation theory in the massive Schwinger model.

How aerosol size matters in aerosol optical depth (AOD) assimilation and the optimization using the Ångström exponent [PDF]
Atmospheric Chemistry and Physics, 2023 Satellite-based aerosol optical depth (AOD) has gained popularity as a powerful data source for calibrating aerosol models and correcting model errors through data assimilation.

Applied Sciences, 2020 One of the ongoing tasks in space structure testing is the vibration test, in which a given structure is mounted onto a shaker and excited by a certain input load on a given frequency range, in order to reproduce the rigor of launch.

Radiative neutrino mass model from a mass dimension-11 ∆L = 2 effective operator
Journal of High Energy Physics, 2020 We present the first detailed phenomenological analysis of a radiative Majorana neutrino mass model constructed from opening up a ∆L = 2 mass-dimension-11 effective operator constructed out of standard model fields.

The Null Decomposition of Conformal Algebras [PDF]
, 2006 We analyze the decomposition of the enveloping algebra of the conformal algebra in arbitrary dimension with respect to the mass-squared operator. It emerges that the subalgebra that commutes with the mass-squared is generated by its Poincare subalgebra ...

Mass Operator and Dynamical Implementation of Mass Superselection Rule [PDF]
Annales Henri Poincaré, 2012 We start reviewing Giulini's dynamical approach to Bargmann superselection rule proposing some improvements. We discuss some general features of the central extensions of the Galileian group used in Giulini's programme, focussing on the interplay of classical and quantum picture, without making any particular choice for the multipliers.
