The ongoing search for the dark photon conducted under the IMSA-CMS research collaboration relies on a boosted decision tree (BDT) for signal classification. BDT robustness is necessary to ensure an unbiased and model-independent search. We analyze the performance of a boosted decision tree classifier against empirical data collected by the CMS Experiment at the Large Hadron Collider and simulated data ... Read More

We analyze signal and background for our doubly charged Higgs boson analysis using Monte Carlo simulations. The focus of this research is to model the uncertainties in our Monte Carlo simulations including rate systematics, which affect the overall normalization of the Monte Carlo, and shape systematics, which affect the shape of the distributions. The aim of the systematic framework is ... Read More

One theory of dark matter predicts the existence of a dark sector, which is a theoretical complementary model to the Standard Model of particle physics. Within this model there must be a particle responsible for the dark analog to the electromagnetic force, which we would call the dark photon. The premise of our research is based upon electron jets that ... Read More

Many theories, including several dark sector models, predict the existence of dark photons to explain dark matter as an extension beyond the Standard Model which interacts sparsely with Standard Model particles via kinetic mixing. The decay of dark photons is theorized to primarily decay into lepton jets that contain oppositely charged dileptons. In our Monte Carlo simulation, we see dilepton ... Read More

To investigate theories beyond the Standard Model, Monte Carlo simulations are utilized to model particle collisions and glean valuable information to inform searches for exotic particles. In our search for the doubly charged Higgs Boson, we seek to validate the accuracy of our Monte Carlo simulations with this study. Specifically, events with two leptons are analyzed in-depth, serving as a ... Read More

Four-dimensional quantum field theories with N=2 supersymmetry provide a rich theoretical laboratory to test general ideas about quantum field theory. A large class of such theories, known as Class S, arise from compactification of a six-dimensional N = (2,0) theory on a punctured Riemann surface. The N = (2,0) theories have an ADE classification, and those of type A,D, and ... Read More

In high-energy physics experiments, the accurate application of systematic scale factors is essential for refining analysis, specifically in the context of muon and electron identification. These scale factors are derived from empirical data to correct for various effects in the reconstruction and identification processes in the Monte Carlo simulation. We present a method for applying systematic scale factors, focusing on ... Read More

Many theories beyond the Standard Model (SM) predict a doubly charged Higgs-like particle that can be pair-produced in hadronic interactions via a Drell-Yan-like mechanism. Specifically, the left-right symmetric model, which solves parity violation in the weak sector, predicts a Higgs triplet(non-SM neutral, singly-charged, and doubly-charged Higgs). The doubly-charged Higgs(H++ and H--) is chosen for its unique event signature: a pair ... Read More

Currently, the most accurate model at describing observations in particle physics is the Standard Model. However, there are many phenomena that it fails to explain, such as dark matter: an unknown type of matter detectable only by its gravitational effect on regular matter. One explanation is that it is made of many different undiscovered dark matter particles in a "dark ... Read More

The doubly charged Higgs boson is a beyond Standard Model (BSM) scalar that arises from many left-right symmetric models. These theories aim to explain the left-right asymmetry from the weak force in the Standard Model by introducing an SU(2)_R gauge group. From this, the doubly charged Higgs boson is a result of spontaneous symmetry breaking which predicts the existence of ... Read More

Pulse shaping, which is the modification of the physical waveforms, is often used to control the behavior of quantum technologies. By tailoring the amplitude and phase of pulses, pulse shaping can be utilized to enhance fidelity or adjust the sensitivity of the basic operations in quantum communication and computing. Most modern error mitigation tries its best to avoid pulse shaping, ... Read More

The Standard Model is a theory that classifies all of the known elementary particles and the forces that mediate their interactions. However there have been theories proposed which extend the Standard Model that imply the existence of the doubly charged Higgs boson. This theoretical particle decays into Standard Model leptons that can be detected and measured in current particle colliders. ... Read More

The doubly charged Higgs boson is a particle predicted by various theoretical models such as the left-right symmetric Model. Using data from the CMS detector at the LHC in collaboration with Fermilab, we reconstruct signal events while making cuts to minimize background detection. The Higgs Boson is predicted to have a decay that results in two same-sign leptons. In order ... Read More
