On a realization of {β}-expansion in QCD
Journal of High Energy Physics, 2017 We suggest a simple algebraic approach to fix the elements of the {β}-expansion for renormalization group invariant quantities, which uses additional degrees of freedom.

Off-shell divergences in quantum gravity
Journal of High Energy Physics, 2023 We investigate off-shell perturbative renormalisation of pure quantum gravity for both background metric and quantum fluctuations. We show that at each new loop order, the divergences that do not vanish on-shell are constructed from only the total metric,

Localization of Gauge Theories on the Three-Sphere [PDF]
, 2012 We describe the application of localization techniques to the path integral for supersymmetric gauge theories in three dimensions. The localization procedure reduces the computation of the expectation value of BPS observables to a calculation in a matrix

Multi-collinear splitting kernels for track function evolution
Journal of High Energy Physics, 2023 Jets and their substructure play a central role in many analyses at the Large Hadron Collider (LHC). To improve the precision of measurements, as well as to enable measurement of jet substructure at increasingly small angular scales, tracking information

Renormalized measure of regular languages [PDF]
International Journal of Control, 2006 This paper modifies the signed real measure of regular languages, which has been reported in recent literature for analysis and synthesis of discrete event supervisory control laws. A new concept of renormalized measure is introduced to eliminate a user-selectable parameter in the present version of the language ...

Effective action for the Yukawa model in curved spacetime
Journal of High Energy Physics, 2018 We consider the one-loop renormalization of a real scalar field interacting with a Dirac spinor field in curved spacetime. A general Yukawa interaction is considered which includes both a scalar and a pseudoscalar coupling. The scalar field is assumed to

Line defect RG flows in the ε expansion
Journal of High Energy Physics, 2023 A general analysis of line defect renormalisation group (RG) flows in the ε expansion below d = 4 dimensions is undertaken. The defect beta function for general scalar-fermion bulk theories is computed to next-to-leading order in the bulk couplings ...

Optimal designs for indirect regression [PDF]
, 2004 In many real life applications, it is impossible to observe the feature of interest directly. For example, scientists in Materials Science may be interested in detecting cracks inside objects, not visible from the outside. Similarly, non-invasive medical

One-loop diagrams with quadratic propagators from the worldsheet
Journal of High Energy Physics, 2022 It is well known that forward limits of tree-level amplitudes (and those trivalent diagrams they consist of) produce one-loop amplitudes and trivalent diagrams with propagators linear in the loop momentum.
