Bottom quark forward-backward asymmetry at the future electron-positron collider FCC-ee

M. Cobal, Giovanni Guerrieri, Hamzeh Khanpour, Giancarlo Panizzo et autres

The Standard Model (SM) prediction for the \PZ-boson pole $b$-quark forward-backward (FB) asymmetry is: $(A_{FB}^{0,b})_{th} = 0.1030 \pm 0.0002$. The LEP electron-positron collider measured instead $A_{FB}^{0,b} = 0.0992 \pm 0.0016$, value which presents the largest discrepancy with any of the SM predictions …

Climbing to the Top of the ATLAS 13 TeV data

G. Aad, Erlend Aakvaag, B. Abbott, Sara Abdelhameed et autres

The large amount of data recorded with the ATLAS detector at the Large Hadron Collider, corresponding to 140 fb$^{−1}$ of pp collisions at a centre-of-mass energy of $\sqrt{s}$=13TeV, has brought our knowledge of the top quark to a higher level. The measurement …

Performance and efficiency of a transformer-based quark/gluon jet tagger in the ATLAS experiment

Georges Aad, Erlend Aakvaag, B. Abbott, Sara Abdelhameed et autres

A deep-learning approach based on the transformer architecture is developed to distinguish between jets originating from quarks and gluons. The algorithm operates on jets with transverse momentum $p_{\text{T}} > 20$ and pseudorapidity $|η| < 4.5$ and takes as input several properties derived …
