Supersymmetry (SUSY) is one of the most active fields of research in high-energy physics and particle physics. However, SUSY is not so easily accessible for students wishing to get started on this field of research due to complexities often associated with quantum field theories. In this talk, I'll discuss some aspects of SUSY in the context of quantum mechanics. In particular, I'll...
Our ability to completely understand the size of the proton has come into question. This puzzle is presently unsolved. It has been building up since 2010 when a measurement of the Lamb shift in muonic hydrogen yielded a very precise value$^1$ for the electric charge radius of the proton equal to $\langle$r$^2$$_E$$\rangle$$^{1/2}$ = 0.84087(39) fm with an amazing 0.1% uncertainty. This...
We study the cosmology of a recent model of supersymmetry breaking,
in the presence of a tuneable positive cosmological constant, based on a
gauged shift symmetry of a string modulus that can be identified with
the string dilaton. The minimal spectrum of the ‘hidden’ supersymmetry
breaking sector consists then of a vector multiplet that gauges the shift
symmetry of the dilaton multiplet and...
We argue the classical Ising model coupled to 2d dynamical simplicial geometries and show that even though the Ising model is classical, the Curie
temperature can reach the absolute zero by tuning a parameter
controlling simplicial geometries. This talk is based on a work in
progress with Tomo Tanaka in Rikkyo University, Japan.
We use holographic techniques to compute inflationary non-Gaussianities for general single-field inflation, including models with a non-trivial sound speed. In this holographic approach, the inflationary dynamics is captured by a relevant deformation of the dual conformal field theory (CFT) in the UV, while the inflationary correlators are computed by conformal perturbation theory. In this...
To measure the properties of top quark, it is crucial to identify events containing top quark pair first by using discriminators. Currently cut-based discriminators are used to identify such events. This, however, may lead to inaccuracy due to the fact that cut-based discriminators might exclude collision events including top quark pair, or, even worse, include background events in which top...
In the near future, experimental studies of charmed baryon productions will be carried out at $\bar{\text{P}}\text{ANDA}$ and J-PARC. In the $\bar{\text{P}}\text{ANDA}$ experiment, charmed baryon productions will be studied in proton-antiproton annihilation reactions. At J-PARC, the spectroscopy study of charmed baryons via the pion induced reactions at a high-momentum beam line will be...
