10 TeV Müon Çarpıştırıcısında Anormal Higgs-Ayar Bozonu Etkileşimlerinin Araştırılması

Öz

Gelecek müon çarpıştırıcısında μ- μ+ → W- W+ Z süreci boyunca anormal HγZ, HZZ ve HWW köşeleriyle ilişkili olan altı boyutlu operatörlerdeki Wilson katsayıları üzerindeki duyarlılıkları araştırıyoruz. 10 TeV kütle merkezi enerjisi ve 10 ab−1 ışınlılık ile tasarlanan müon çarpıştırıcısında Higgs-ayar bozonu etkileşimlerini içeren sinyal olayları ve ilgili arka plan olayları, modelden bağımsız Standart Model etkin alan teorisi çerçevesinde MadGraph’ta üretilir. Bu olaylar, parton duşlaması için Pythia’dan geçirilir ve müon çarpıştırıcısı detektörünün gerçekçi detektör etkileri için Delphes tarafından simüle edilir. c ̅HB ve c ̅HW katsayıları üzerindeki %95 güven aralığındaki sınırlar, sırasıyla [−0.00026; 0.00026] ve [−0.00017; 0.00018] olarak elde edilir, bulunan bu sınırlar mevcut deneysel ve fenomenolojik sınırlar ile karşılaştırılır.

Investigation of Anomalous Higgs-Gauge Boson Couplings at 10 TeV Muon Collider

Öz

We investigate the sensitivities on Wilson coefficients in dimension-six operators associated with anomalous HγZ, HZZ, and HWW vertices along the μ− μ+ → W- W+ Z process at future muon collider. At the muon collider designed with a center-of-mass energy of 10 TeV and an integrated luminosity of 10 ab−1, signal events involving Higgs boson interactions and related background events are generated in MadGraph within the framework of the model-independent Standard Model effective field theory. These events are passed through Pythia for parton showering and simulated by Delphes for realistic detector effects of the muon collider detector. The limits on c ̅HB ve c ̅HW coefficients at 95% confidence level are obtained as [−0.00026; 0.00026] and [−0.00017; 0.00018], respectively, and these limits are compared with existing experimental and phenomenological limits.
