LLM-Based FORM Code Generation with Verification-Driven Fine-Tuning
Bakar Chargeishvili
FORM is a domain-specific symbolic manipulation language widely used in particle physics for processing the very large algebraic expressions arising from multi-loop Feynman diagram…
Higgs boson pair production in SMEFT: shape and truncation studies
Manosch Bär, Bakar Chargeishvili, Ramona Gröber +2
We present a comparative study of the influence of Wilson coefficients on Higgs boson pair production cross sections in SMEFT up to dimension-6, also including loop-suppressed oper…
Analysis of and -parton contributions for computing QCD jet cross sections in the local analytic subtraction scheme
Bakar Chargeishvili, Giuseppe Bevilacqua, Adam Kardos +2
We analyze and implement the Local Analytic Sector Subtraction (LASS) scheme for handling infrared singularities in next-to-next-to-leading order (NNLO) calculations in perturbativ…
LASS, the numerics
Adam Kardos, Giuseppe Bevilacqua, Bakar Chargeishvili +2
We summarize our efforts to create a numerical implementation of the Local Analytical Subtraction Scheme (LASS) for obtaining NNLO QCD predictions in electron-positron collisions.…
Automatic generation of orthogonal multiplet bases in color space
Bakar Chargeishvili
We present a software that automatically generates a multiplet color basis for general processes in quantum chromodynamics (QCD). The construction process is guided by th…
One-loop soft anomalous dimension matrices for hadroproduction
Bakar Chargeishvili, Maria Vittoria Garzelli, Sven-Olaf Moch
We calculate the one-loop corrections to the soft anomalous dimension matrices for the production of a top-antitop quark pair in association with a jet at hadron colliders. This is…
Beyond the Standard Model Physics at the HL-LHC and HE-LHC
X. Cid Vidal, M. D'Onofrio, P. J. Fox +294
This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in…
