It is an autonomous institute fully funded by the Department of Atomic Energy, Government of India. Till October 10, 2000 the Institute was known as Mehta Research Institute of Mathematics and Mathematical Physics (MRI) after which it was renamed as Harish-Chandra Research Institute (HRI) after the internationally acclaimed mathematician, late Prof Harish-Chandra. The Institute started with efforts of Dr. B. N. Prasad, a mathematician at the University of Allahabad with initial support from the B. S. Mehta Trust, Kolkata. Dr. Prasad was succeeded in January 1966 by Dr. S. R. Sinha, also of Allahabad University. He was followed by Prof. P. L. Bhatnagar as the first formal Director. After an interim period in January 1983, Prof. S. S. Shrikhande joined as the next Director of the Institute. During his tenure the dialogue with the Department of Atomic Energy (DAE) entered into decisive stage and a review committee was constituted by the DAE to examine the Institutes fu- ture. In 1985 N. D. Tiwari, the then Chief Minister of Uttar Pradesh, agreed to provide sufficient land for the Institute and the DAE promised financial sup- port for meeting both the recurring and non-recurring expenditure. -

Mathematical Physics and String Theory
TIFR Annual Report 2001-02 THEORETICAL PHYSICS String Theory and Mathematical Physics Tachyon Condensation and Black Hole Entropy Condensation of tahcyons in closed string theory was analyzed and its connection with the computation of the black hole entropy was pointed out. The entropy computed in this manner was found to be in precise agreement with the the Bekenstein-Hawking Entropy. [Atish Dabholkar] Tachyon Potential and C-function A tachyon potential with the appropriate critical points was proposed in terms of an effective c-function of the worldsheet theory and it was determined as a solution of certain integrable equations. [Atish Dabholkar and C. Vafa of Harvard University] D-branes in PP-wave Backgrounds Dirichlet branes in the background of a PP wave were constructed and the open string spectrum was in agreement with the gauge theory spectrum. [Atish Dabholkar and Sharoukh Parvizi] Loop Equation and Wilson Line Correlators in Non-commutative Gauge Theories Loop equations for correlators of Wilson line operators in non-commutative gauge theories were derived. Unlike what happens for closed Wilson loops, the joining term survives in the planar equations. This fact was used to obtain a NEW loop equation which relates the correlation function of an arbitrary number of Wilson lines to a set of closed Wilson loops, obtained by joining the individual Wilson lines together by a series of well-defined cutting and joining manipulations. For closed loops, we showed that the non-planar contributions do not have a smooth limit in the limit of vanishing non-commutativity and hence the equations do not reduce to their commutative counterparts [Avinash Dhar and Y. -

Rajesh Gopakumar
Rajesh Gopakumar Research Summary: In the last year, I have continued to build on my attempts to reconstruct the string worldsheet theory dual to free large N Yang-Mills theory. In work with Justin David, we obtained the explicit form of the worldsheet correlators for a special class of field theory correlators. The explicit form exhibited a number of prop- erties expected of worldsheet correlators such as manifest crossing symmetry. The precise form of the answer also shows potentially interesting connections to correlators of the 2d Ising model. In work with O. Aharony, J. David, Z. Komar- godsky and S. Razamat, we studied another aspect of the worldsheet correlators which arises in the case of certain free field diagrams. This is the issue of locali- sation on moduli space of the corresponding worldsheet correlators. We studied how this arises in some detail and found an interesting connection between the localisation on moduli space and the lack of space-time contractions between the corresponding field theory operators. We are continuing to investigate these and other aspects in trying to learn some general lessons about the worldsheet theory. Another strand of research has been to study black holes in Anti-de Sitter spaces using the gauge-gravity duality. With Suvankar Dutta we tried to see how the membrane paradigm might be realised in the specific context of the AdS/CFT duality for black holes in AdS spaces. We have also been studying the physics of charged black holes in AdS5 with the hope of quantitatively comparing the thermodynamics of near extremal black holes at weak and strong coupling. -

Conformal $ N $-Point Functions in Momentum Space
Conformal n-point functions in momentum space Adam Bzowski∗ Department of Physics and Astronomy, Uppsala University, 751 08 Uppsala, Sweden. Paul McFaddeny School of Mathematics, Statistics & Physics, Newcastle University, Newcastle NE1 7RU, U.K. Kostas Skenderisz STAG Research Center & Mathematical Sciences, University of Southampton, Highfield, Southampton SO17 1BJ, U.K. We present a Feynman integral representation for the general momentum-space scalar n-point function in any conformal field theory. This representation solves the conformal Ward identities and features an arbitrary function of n(n − 3)=2 variables which play the role of momentum-space conformal cross-ratios. It involves (n − 1)(n − 2)=2 integrations over momenta, with the momenta running over the edges of an (n − 1)-simplex. We provide the details in the simplest non-trivial case (4-point functions), and for this case we identify values of the operator and spacetime dimensions for which singularities arise leading to anomalies and beta functions, and discuss several illustrative examples from perturbative quantum field theory and holography. I. MOTIVATION recent efforts, all the necessary prerequisites are now in place. Firstly, the momentum-space 3-point functions The structure of correlation functions in a conformal of general scalar and tensorial operators are known, in- field theory (CFT) is highly constrained by conformal cluding the cases where anomalies and beta functions symmetry. It has been known since the work of Polyakov arise as a result of renormalization [34{46]. Secondly, [1,2] that the most general 4-point function of scalar momentum-space studies of the 4-point function have yielded special classes of solutions to the conformal Ward primary operators ∆j , each of dimension ∆j, takes the form O identities [15, 32, 47{51].
